If you back out into the main menu while you have the blindfold on and start a new game, then the blindfold's visual effect will be active, but without the restricted vision range, also it kinda blocks the minimap, but not how it's supposed to. (this bug was also present in previous versions, I was just too lazy to write a bug report)


Equipping and then unequipping the blindfold resolves the visual bug, equipping other items, even if they slot into the same spot, like the new blinders does not.
The bug is pretty hard to happen on and worst case scenario a full restart of the game resolves it, but it might screw with saves or if other new visual effects are implemented.
