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'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).
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.
