Welding rig/welder not working?

Edit/Okay, scratch that. I am an idiot, i forgot i need welding goggles.

In ba3d403 build, if i load up the save in my previous copy, 738e5e8, it suddenly works… is it my issue or something got broken?

Edit/ Downloaded the latest, 8b38e05, still not working (showing as red in the vehicle crafting men). Btw, it works well with normal crafting or reinforcing metal stuff.
