Squad pathfinding bug[getting stuck in structures video link]

[unmerged(729010)]

I have been experiencing a bug where my squad units get stuck in structure while moving in dungeon, this mostly occur when moving multiple units mostly in groups of 3+ squads, I know this bug is minor as it can be circumvented and solved by teleporting the squad out of the situation, but teleporting them also drain on the aggressiveness so would be nice to see a fix for it, links below:
