I´ve noticed a few Issues with the Skeleton Archers AI or maybe with the handling of terrain which is blocking the shooting path.
Doors - Archers can only shoot in a very little angle through doors in the temple of eterra. Most of the arrows are lost because they “hit” the door. (of course not. the door is 3 miles wide open^^)
The doors on the screenshot are btw the first doors ive noticed it. i dont think this happend with the ruin field doors in ruins of welryn.
Stairs - Also the Archers have problems to notice they cant hit the targeted enemy because they shoot the stair and not upwards to the enemy.
Golems - Golems block also the arrow path. I might think this is logical but its also very annoying because you dont have a move command for your minions and if the golem means to hit the big mob standing in a doorway while your only dmg dealers standing right behind him but cant do any damage…you know it sucks ^^
Feel free to hit me up if you have any questions to the report.
