Sinclair using Mo's combo against rabbits crashes the server

[Gilational]

Similar to https://forums.playdeadlock.com/thr...imate-interaction-causing-server-crash.53849/ but more specific information

Occurred in match, though the server crashing meant the match was never saved. Tested in sandbox.

Reproduction steps:
1) Sinclair copies Mo's Combo ability
2) Sinclair uses Combo against target
3) If target is a rabbit (hexed) and is killed by the combo ability, the server crashes

What does not cause this crash:

• Mo killing a rabbit (hexed) target using Combo (hexed target)
• Rabbit (hexed) targets of combo not dying

I have not tested what occurs if the target dies during combo when the target starts as a rabbit (hexed) and end non-hexed, as a separate bug makes this unreasonable for a single person (Combo stops dealing damage after target is un-hexed, will post a separate thread)
