I crafted a signum and I am unable to retrieve it from the crafting area. I waited overnight and tried again in the morning and I am still unable to collect it. Because of this I am unable to craft any further items.
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.
I fixed it by just doing a mission... after the mission i could retrieve the item
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'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).
