This error comes out of this replay:
https://zero-k.info/Battles/Detail/2472912

running this mod: https://zero-k.info/Mods/Detail/31

The mod changes stuff about commanders, and is most likely an interaction with code from the commander egg update.

Probably just needs a change to return false when it's given an improper unit def ID and let errors scream elsewhere.
