Further info. I looked up the current GLO_PartyMembers script in a blank Origins mod.

That DOES include PROC_GLO_PartyMembers_Kick_PartyMembers_Restore in many places.

The one I have in the ZIP does not have this. It was either removed Amereth (who helped get this going) or added after the game was released, because this char creation patchwork was created before release.

So I'd either just slash it all out of your file or via comment. Or use my zipped file.

If you're using your own, make sure to put in the INIT section:
DB_CC_MaxPartySize(4);
