ScheinNightfire: It sounds like you're past this, but . . . if you go to the party Add/Remove screen you can just add Atton and Kriea to your party so you don't have to solo Telos after B4-D4. It's annoying, but easy enough to fix.
I've come across some of the other bugs mentioned in this thread (Atton not turning around and the T3-M4 dialogue skippage) but I haven't seen this one yet.
SPOILER-ish below.
This occurred on Dxun, while trying to get Kumus off the ledge with Visas and Disciple in my party. I get him down, say something nice to him, and send him back to the camp. The Disciple then interjects with a few lines that end up in an influence gain, but the influence goes to . . . Atton? You can't even take him off the ship the 1st time on Dxun.
