I recently decided to replay all of BG and BG2, and decided to try them modded. I used the BiG World mod and was able to get through the installation pretty unscathed. However, now I'm running into a minor problem. I'm not able to re-add certain NPCs after I kick them out of the party. The leave party dialogue kicks in for Imoen, Khalid, Jaheira, and Viconia just fine, but every other NPC I've added to my party thus far (Minsc, Dynaheir, Garrick, Finch, Edwin) will just stand there after I remove them from the party and if I talk to them, they say their in-party dialogue. I haven't found a way to re-add these party members
I tried to look for potential fixes here and at gibberlings3, and I thought that I had found a potential solution here, but I wasn't able to find the offending code listed in that topic. I've also attached the weidu.log below for convenience sake

Thanks, any help is appreciated
