X has nothing to say to you Options

[Olbas]

I've encountered a problem while playing IA although I'm not sure it's caused by the mod I was hoping you would be able to help me. Whenever I kick a character out of my party they leave without asking me if they should stay or go and then when I try to talk to them again it says 'X - has nothing to say to you'.
I originally thought this was intentional by IA and so kept on playing. Now I've run into a problem when Jan left for his quest to help a sick girl and when I cured the girl he won't initiate conversation with me to complete the quest and get him back into the party. I read that this is sometimes caused by installing incorrectly and so I re-installed and the problem is gone from my save but only for current party members not ones that already left. I have no save from before Jan left.
Please could you tell me if there is a way to use the console to force the conversation with Jan to occur?

My install order was:

SoA
ToB
Official ToB patch
Baldurdash Fixpack 1.12
Ease of Use
Dungeon Be gone
IA

I am not sure how the problem came up from those.
