Dungeon Core death animations

I've noticed in recent Undergames and skirmish levels that the death animations of some Underlords' cores are broken.

So far I've noticed that Kasita (haven't checked the silver variant yet, but I imagine it will be the same), Zeam and Rhaskos' cores are all lacking proper death animations, i.e. they go from "alive" to "dead" in what seems like a single frame. Sovereign/Marcus, Kickstarter/Draven and Arcane appear to be ok though.

In addition, Zeam's death state also seems to be broken as some textures that should appear solid are transparent instead - these images should illustrate the problem better - just look at each corner of the depressed dungeon core area.

I'll check out the other dungeon themes in due course and add any broken ones to this ticket.
