Howdy! Great mod.
Today I found a bug that seems to to triggered by the Minsc and his quest to find Boo.
After the quest is over (Found boo, Minsc gets his 19str and the boolet upgrade), Minsc no longer has any speech that triggers when you boot him from the group. He just walks up to CHARNAME and stands there. He cannot be spoken to and he stays in that spot even when you leave. You cannot recruit him back since you can't talk to him.
Saving and reloading there doesn't help.
I had a save RIGHT before talking Elenanya to finish the quest (Where Minsc's portrait is still halfsize). Booting him from the group triggers a speech (that he is angry but still I can tell him to go to the copper coronet). Also had a load very close to before boo getting lost. Booting Minsc triggers the normal speeches and I can send him to copper coronet.
So it seems this problem happens right after completing the the quest to find Boo.
I am using BG2:EE with UBv24. (also SCS, atweaks, COM enounters, BG2 tweaks, Banterpacks, sellswords, Backbrynnlaw, Assassinations, Iepbanters. All latest versions). These were the ones that were given a green light as compatible with BG2:EE.
