I've got a bush with a burn trigger on it in front off a wall with a bomb trigger. The idea was burn the bush, than bomb the wall to reveal the door. What's happening though is that when you burn the bush both the burn and bomb trigger are activated. The same is true if you bomb the bush. I tried moving them away from each other, burn another bush, just to see what would happen, and again, if I burn the bush the bomb trigger is activated as well. It seems the problem is when there is a burn trigger and a bomb trigger on the same screen. When I have a burn trigger alone on a screen a bomb has no effect on the burn trigger.
