As the DM, I am not able to see any NPC tokens I drop onto the canvas unless I select a PC token. Once I click off of the player token, the NPC disappears. Players do not have this issue. Players are able to see all visible tokens I drop onto the canvas.
Has anyone had this problem before? I am trying to use the FTC module but so far I cannot seem to figure out a solution. Help is most appreciated.
Try disabling all modules and then creating an entirely new NPC. Does it behave the same way?
Also try creating a new scene. It might be that there’s some z-stacking happening with a tile that’s above the level that the player tokens are on or something 
Though the fact that you can see player tokens is odd, if you can’t see the NPC ones
OKAY THIS IS COOL. I figured it out, and you were close! Man oh man, I really hope this helps some other poor schmuck like me!!
For whatever reason, anytime I create a new NPC token, their “height” value was 0. That was completely F-ing up DM vision. I manually set token heights to 6’ and it all works like a charm.
Now if only I can figure out why NPC defaults are set a 0 feet tall, then I will have it all worked out. LOL
