I came across this last night, and I didn't know if it's actually a bug in the game. I have v1.29beta here.
This is the scenario here:
I have 2 triggers over the SAME area. First one is set to detect for the presence of WEST, and if they are, end the game (win). The 2nd one, exactly the same dimensions, but now detect for the presence of EAST, and for the player to LOSE.
Yeah this mission is kinda like a race, to see who gets to the object first... the player (US troops) must get there before the Russians do, or else.... *cue doomsday music*
Well the thing is, seems like both triggers cancel each other out... none of them activates even with east or west troops being present....
