I had activated the two mod packages "Mod: Conquest Tweaks" and everything.
After "cali" was thrown out of the group due to too little life bar, I didn't think anything about it and continued to play.
When a few (inGame) days later I wanted to pull "cali" back in it didn't go, thought that this is still death-log, when I wanted to (in few inGame days later) someone else in the group it didn't work either.
even when I left with a completely new group, it was not possible to edit the Battle Group.
