I got most of these bugs found and fixed for the next build that will come out soon!
I also was reading your conversation about the glitched weapons.
A while ago, I found that one of the doors in the cabin that Natasha stays in can cause the issue of your weapons not working. Do you remember possibly going through there? If you know the EXACT moment where your guns stopped working that'll help me out a bunch but otherwise I will keep my eyes peeled for more reports of the issue. The door in Natasha's cabin is the only one I know of and it's been patched for the next build.
I will also work on a psuedo fix for all saves in case this issue ever occurs again to other players.
Thank you guys for reporting these issues to me!
