Dreg Tox Flamer is missing the Tox flame pipe that link the backpack and the weapon since the release of the game. (I know it is something really minor and probably will never be fixed, but you never know)
I hope so! There’s so many little bugs like that that I know (small hole in the Valkyrie cough pipe floating on the head of the servitor medicae station instead of touching the head cough), but don’t bother making a bug report for it because I don’t think the dev will bother fixing small thing like that… x)
