Ilshavohs stuck in terrain

[Lieutenant Lich]

Exactly what the title says. I'm sure this isn't new by any means since I've seen this now, last month, last year, and the year before that, and probably longer. It's annoying af and requires additional micro to get the units moving again, only to get stuck again within 0.0001 seconds. Can we finally fix this problem? I understand that ilshies are strong and all but that strength means nothing if 1/4 of them keep getting stuck and unable to free themselves without interference.

Spoiler: show

I'm putting this here because it seems like a texture/mechanic issue. If this belongs in general discussions, I apologize in advance for misplacing this technical thread.
