Hi guys. In one of the threads below I said the smoke grnades were broken and buggy in LW Perk Pack.
THAT IS NOT A PERK PACK ISSUE is would seem.
The game has this problem since launch, and apparently its a UI LOS problem. Like other grenades (flashbang), smoke granede needs to have an clear LOS from it's point of impact to the effected soldier. If it doesn't no smoke is created at that tile! (Similar to flashnabg with the enemies)
However, the UI is buggy, always showing the full field as there are no LOS losses when they are if you land the grenade on the other side f the wall ie.
To fix it use this mod (Reliable Smoke):

This will fix the UI, so you will see if the smoke will effect a give tile. Also it will remove the flanked property for soldier under smoke that can be disabled in the ini.
