What happened when the bug occurred?
 I was trying to craft a shotgun and I had all the materials/skills/furnace and the "Craft" button was white. When I clicked it nothing happen so I tried it with some other guns and pots, and it didin't work. This has happend several times before and I fix it by rejoining, but it's annoying.

What was supposed to happen?
I guess it should let me craft the stuff when I got all the stuff needed.

Picture/Console Errors:
None
