Visibility changes

[DRG]

We have had very similar questions like this in the past and it came down to visibility being blocked due to combat activity between where the unit was and the target hex had changed from earlier in the game and tipped the balance between seeing a distant target and not being able to see it.

Smoke has to reach a certain level before it appears on the map but up to the level that triggers the smoke Icon to first appear on the map there is still accumulation and enough of it can tip the LOS depending on the original game visibility. Lower visibility to start can tip it quicker than higher visibility
