Pretty much the title.
I tried my best to replicate the bug where Kreia, Atton and/or Bao-Dur stop talking to you, but... I can't make it happen at all.
So if anyone has any savegames, or if you had it happen can tell if you recall what you did on the sparring mat (which teammates?, did you loose a fight by cheating?, left the mat? Was the handmaiden still hostile after you said you'd return later?
I've already made a small modification which hopefully makes it less likely to appear, but without replication, I can't make sure it'll never happen again anymore :/
And judging from the Steam forums, it's happening more frequent than ever before...
