I was able to successfully move the Advent culture center research to Tier 0 (1 lab required) for Advent Loyalists ONLY, by removing it as a pre-requisite for the first Advent culture spread rate research.

I did this by creating loyalist-only versions of the culture center module and culture center research entities so the module could be dependent on the research.  The advent rebels still had the research in tier 1 (2 labs) but the dependency was also removed from the first culture spread rate research.

This is OK but I wanted to preserve the original dependencies of all culture research.  I created loyalist-only versions of all research subjects that are dependent on the culture center research (culture vision, resist, psiorbitalcannon + module, etc.).

however, when I try to enable the "full version" of the mod, I get a mini-dump.  I've added all the new entities to the manifest and the PlayerPsiLoyalist.entity.  

Any ideas off the top of your head on what could be going wrong?  It works fine when I have just 2 new loyalist-only entities, but not when I have 10.
