There are mods that add new Xenotypes that have different bodies, such as the Mod https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2927323805 that cause crashes or texture failures.

A possible solution with this compatibility is to add the Kobolds as a Xenotype instead of a complete replacement for the colonists.

Sorry if I'm not clear, I use the translator to be able to publish.
