This hasn't happened to me in a prior pre-Jumpgate campaign, but it's definitely happening now in my current game. When my players use !bump, the strangest thing happens. Any emitting light source now appears to be emitting darkness. So I have a say, an orc with nightvision. He bumps, and his purple square token carries his vision settings over. Cool. But now the human standing near him with a torch is emitting darkness instead of light (in the exact pattern/distance of his torch), disrupting his vision. So basically, light sources are now anti-light sources... an anti-light the orc's darkvision cannot penetrate. Any idea why this might be happening... and how to overcome it?
