[2019] I have come to the conclusion that crafting anything that requires nuclear material doesn't work.

Hi and thanks for your recent reports! We've been looking into the issues you've mentioned across a few different threads, and through investigation found that if you take all of your Ultracite and Nuclear Material out of your Stash and then put it back in, that should help resolve the troubles you've been having with crafting, repairs, and object placement.

Can you give that a try and please let me know if it helps to fix any of these issues? Thanks very much!
