I've returned to creating my campaign after a while. I've patched my version of game and then noticed that on 2 of my maps (1 of them is for a long time available on Mapster) there's a bug now.
The bug is funny. I created a "background" on this 2 maps - on the level -1 of terrain is taking place a battle between computer. What fuc*ed up - well, the range units are now sending their missiles to the level 0! (up), not to the enemy unit at -1! I'll show you on the screenshots:
From 1st map - cannons (not quite good screenshot):
From 8th map - stalker and caracan:
Is there any way to fix it? I'm personally little upset that the Blizzard a little ruined my concept of maps with the battle background at -1 lvl of terrain. :/
