I think you meant "sistersbuildbasestrategy.ai" as this should be impacting only ONE faction... Sisters... don't want to over-complicate things of course.
Btw, if its a loader issue you'll likely start not loading the Unitstats.ai and get something more close to:
CpuManager: No unit stats available for: ultra_marine_squad_builder!!! Using default tactic... Warning: ultra_marine_squad_builder has no unit strength! *ALERT: MilitaryManager:Update() threw exception (lua runtime error) Lua Core/cpu_manager.ai Ln 1564 (?)
