I think I managed to fix this issue for the next update. Thanks again.

I think a lot of this problem will be rectified when I revise some of the datapad UI to be more time efficient. I'm working on parts of that right now.

Thanks for reporting this. I'll be taking a look soon.

Breaking them will result in a "Broken Canister" which can be salvaged for reduced materials. The chance of breaking them on use was my way of making it less punishing because you wouldn't lose the oxygen in the tank, but at the same time it's also more "dramatic" because it would happen while you're on an EVA instead of annoying if it happened during crafting. I feel like if it happened during crafting you would just be like, "ugh, okay, guess I'll just craft a new one right now". That was my thought process anyway.

Yeah, the empty tank is returned to your inventory after you use a filled tank. I will be introducing a chance for oxygen filled containers to break after using them in order to encourage crafting new ones. Right now I think there are just too many available tanks by searching supply caches that you never need to craft new ones.

Sorry, I should have been more specific. Do you craft the empty ones? Or do you just refill empty ones that you've found?

Another question. Do you ever craft them? Or do you just use ones that you find?

That was introduced by me preparing to make these changes to the battery items without double checking the icons. It will be fixed soon.
