Why do life crystals take metal detector priority over hardmode ores?

When you have a metal detector and you're near both a life crystal and a hardmode ore such as titanium, the metal detector will say "Life Crystal detected nearby!". My question is, why would the life crystal would take priority over the titanium when the titanium would be far more important to you in the stage of the game when you're looking for it?

Sorry if I worded that strangely, it's kinda hard to explain.

Do the crystal detectors of crystal radios eventually wear out, and if so, over what length of time?

Edit: quote from source:

"As I fiddled with the contact points, I eventually ruined the crystal. Under the microscope I could see copper smeared on the surface of the galena." β€”http://www.hanssummers.com/images/stories/k0iye/chap04.pdf

Though I think he's here referring to a DIY point-contact transistor, not a point-contact/crystal diode.

Crystal radio detectors

Not sure if this is the correct subreddit.

I know that crystal radio and trf radio detectors can be a germanium diode,ta 7642 IC, MOSFET,Schottky diodes etc, my question is what other semi conductors or ic's ( I know blue razor blades and Galena can be used) could be used as a detector in a radio ?

Need help with a Crystal Radio Detector

I have been working on a crystal radio for about a week now and I decided to go all in an build a cats whisker crystal detector from pyrite. When I connect the crystal to my scope and supply it with a 10khz sine wave I notice that the positive half of the wave is being cut rather than negative half. I thought it would be a simple fix to just switch it around but it still is only the positive half cut. I don't know if this is whats supposed to happen or if I did something wrong. I can post pictures if it helps.

PSA: Metal Detector Prioritizes Life Crystal Over Chlorophyte (and Every Other Block except for Life Fruit)

Sorry to make a PSA over something that's similar to another post but that was over life fruit not life crystals. Anyways, this can be a huge problem because many people would expect chlorophyte to be higher priority as it won't spawn until hardmode, which is when you would likely have all your life crystals... But this is not the case. In fact, right after I realized I should probably make a PSA about this, I found a group of 24 chlorophyte while my metal detector showed life crystal.

EDIT: Sorry for changing the flair over and over, the wiki shows it's pc in one place and all versions on another. EDIT 2: Guess that's my fault... The desktop icon for the item doesn't show if you're on it's page... as confusing as that sounds.

Retreat, Hell - Episode 18

A/N: Hey, guys! Finally got this episode hammered out! We're into Act IV and back on the offensive!

This episode is a bit short, for what they have been lately, only 8600 words or so, but we're getting back into the action.

I've got a good handle on what happens in Episodes 19 and 20, decent outlines for both, and 17.5 and 18.5 half-episodes, though future updates will continue to be slow. I'm moving at the end of the month, and work will continue to be busy right up until I leave. Hopefully I'll have everything set up and settled into my new place by the end of February, and I'll be able to get into a more regular posting schedule after that. The new job is a much lighter workload, and I should have a lot more free time to do all the things I want to do outside of work.

I've got some maps of Gahla that I've been working on, too, that I'll be sharing here at some point. They still need some work before I'm happy with them, and the map files are also on my desktop which is on its way to a container ship with the rest of my household goods, so it'll be bit before I'm able to share them.

Once I get settled into my new place, I'll also be looking to start commissioning character and story art again, since I'll have more time to reach out to and work with artists.

In the meantime, though, here is the next episode!

Powerless (part 1)

Garl'Vohn stalked down the halls, an anger gnawing at his chest. Those damn mahn'ewe; this time they'd gone too far, and left evidence. Of course, they would deny this as 'another rogue vessel', but at least this time he had the satisfaction of knowing that the mahn'ewe responsible for this were actually the ones put to death for it. A small victory, but at this moment, he'd take any victory he could get. This was certainly a situation that they hadn't ever been trained for, and one that leant itself to a major loophole. A loophole that threatened to turn the galaxy as they knew it into a nest of chaos. Such has usually been the case when a species is introduced to technology far beyond their current level of progression. The mahn'ewe would - allegedly - send out scouting ships to planets with sapient species that may be nearing FTL capabilities. They - allegedly - then preform many experiments that Garl'Vohn frankly didn't want to think about, so they would then have the cutting edge on everything from the best gadgets/tools to market specifically for them, to physiological weaknesses needed to exploit them should they prove to be a threat. Well, this time they took a bite out of something before ensuring that it couldn't bite them back, and that's what it apparantly did.

As the chief of the space station's security detail, Garl'Vohn was responsible for dealing with the mess that those gray, empathy-deprived bastards had dropped so heavily in his lap. The gah'rahtoe ship that'd hailed the station reported having come across a mahn'ewe ship drifting lifelessly in the void. When hailed, no response was ever given - though a single life form was detected in the scans - so the ship's security team of 8 boarded the derelict, and found a massacre. mahn'ewe blood was sprayed all over - obviously a few days old, having dried up long ago - with impact marks all over the ship as if some hulking beast went on a rampage, too bulky to easily fit through the narrow halls made for the diminutive creatures, who stood at a paltry 3 feet tall. The halls topped out at 4 feet, meaning the 8 foot tall gah'rahtoe were going through on all fours; luckily they were built for either bi- or quadripedal locomation. The security team cleared the ship, noting the destruction, and the readings that the jump core was dangerously close to a meltdown. They were just getting ready to salvage what could be found when a general alert went out through the team: the survivor had been
