I'm very keen to try more crafting and have limited gaming time this weekend so that is the only reason Ill be attempting a full wipe/restart, that and I restart often anyway (prevents me getting too attached/accustomed and reliant on a characters progression).

Might try deleting all characters and inventory tonight and start over see if that clears the crafting tab issue, I tend to restart characters often at this stage anyway to force me into trying new builds.

I am sure the Neocore team are on it and will have the bug resolved soon.

I fixed it by just doing a mission... after the mission i could retrieve the item

I've created a new character after my boltgun (and autogun) got stuck, but unfortunately the boltgun from my previous character is still there and I can't claim it.
