Frame drops when a Vyper dies

[murilomarian.mm]

I'm not sure why, as I can't seem to find other people with the same problem, but most times when Vyper dies I get really bad frame drops. I usually play with around 90fps, but when a Vyper dies, even if it's on the other side of the map, my frames drop to around 30 until the corpse despawns. This happens 8 times out of 10 when she dies.

For clarification, I don't need to be playing as Vyper for this to happen
