I'm getting a bunch of red text even after I deactivated everything else (except Harmony, HAR and Bulk Carrier) :( They're all variations of the following:

Could not resolve cross-reference: No RimWorld.BodyTypeDef named Baby found to give to AlienRace.AlienPartGenerator+BodyTypeOffset AlienRace.AlienPartGenerator+BodyTypeOffset
UnityEngine.StackTraceUtility:ExtractStackTrace ()
Verse.Log:Error (string)

System.Threading.QueueUserWorkItemCallback:System.Threading.IThreadPoolWorkItem.ExecuteWorkItem ()
System.Threading.ThreadPoolWorkQueue:Dispatch ()
System.Threading._ThreadPoolWaitCallback:PerformWaitCallback ()

I just came back to the game after a while (so the last 6 hours have been spent cursing at mods rather than playing) so I don't know yet whether this actually breaks anything that I'll only notice after 500 hours in but from my lay experience it looks like there's something fundamental missing?
