Lost Warlord frame bug

[SoulLord]

I found a weird frame bug with Lost Warlord unit. Everytime i summon a Lost Warlord, be it red or blue, and i click a single unit, there's not much to notice, but when i click multiple warlords, like 4 or 5, the game lags a bit for some reason. The more you select, the more the frames tank, and when you select all 12 Lost Warlords, be it blue or red, the frames drop so much it's basically unplayable.

Btw, i tried to upload the video to show the bug, but due to it's 4 mb size it's impossible even when heavily compressed, so it's for the best if you see this bug for yourselves in the Forge, cause that's where i found the bug.
