Act 2 stage: Upstairs/Downstairs has bugged pathfinding?

[Dark]

So general rule of the game I've noticed: excluding sappers, enemies will only attack barricades directly as long as there is still a traversable path to any of the rifts on the map.

This rule seems to be nulled after the second wave of the stage Upstairs/Downstairs, as the pathfinding will ignore the fact that the map has two rifts, forcing orcs to go to the downstairs rift (which is designed to be walled off).

I will note, the pathfinding does work properly on the first and second waves, but after that, they will begin to attack the barricades instead of heading up the stairs. Additionally, for anyone trying to reproduce this error, I placed the three barricades as close to the rift, under the bridges, as possible while keeping it walled off.

It's not bugged. The orcs do not have a direct path to the rift. The orcs from both sides are actually 2 "sets" of orcs. Some want to go to the rift above, some want to go to the rift below. The ones in wave 1 and 2 want to go to the one you have not blocked off.

It can sometimes bug out though, unrelated to the map, if you squeeze the barricades too tight or there's a lot of orcs, so they can't pass through their friends in the front, and they'll start randomly hitting barricades, annoying when it happens.

when i completed it the orcs would just stand in front of the baricades dumb founded and not attack but larger enemys would move upstairs
