I've set up a map with walls drawn in the dynamic lighting layer, and when I went to test it I have a problem that I haven't found in other forum posts. I have a player token that I select and then use Ctrl-L to see its POV. This works fine when the token is stationary, and for the first few moves, but after I move the token a few times it stops revealing new areas and its vision seems to switch off. This isn't fixed by toggling either Explorer Mode or Update when Token Drop. The only way I can fix it is by toggling dynamic lighting off and on again, and then resetting the fog of war.
