So I got a Flying Slash broadsword while exploring. I brought it with me into the Mining Facility mission and tried to swap it with a blink slash sword I had. The moment I click on the flying slash sword in my inventory, it first warps me back to my ship for a fraction of a second then completely crashes my game. If not for the error report shown above, I would never have known it was this sword that caused the issue.
I tested it by going back in and messing with them. I picked up and swapped around the blink one with other stuff, nothing happened. Did the same with the flying one and immediately crashed and verified it was the fly slash sword. Idk what's so unique about this thing that it crashes me. My first thought was to scrap it in the Uncrafter and be done with it but then thought I'd bring it up here in case you guys wanna lookit the thing. When this other character finishes the mission and is able to access the Guild, I'll hand it to my main to hold onto (if I can, haven't tried shift clicking into a container yet) and maybe do some more tests until you guys decide what should be done with it.
