This seemed to pop up this weekend (or I just noticed it this weekend).
GM Cntl-L view does not show any other light sources other than the token you selected. Players view is unaffected and works as expected, just GM Cntl-L is.
Example:
This is the normal GM overview. KH-A10 token has 'has sight' The torch is lit with "All players see light" and the guy in top right with the flashlight is also.
This is what Cntl-L gives me:
As GM doing Cntl-L on him, I cannot tell he can see the torch, or the other player at all. All it is rendering the light the token I am checking generates. While to him it actually looks correct.
