Hi, after updating all nightly this morning,
I went in a group and deleted one active member.
now the group infos says 15 users, but when I look into user tab, it's written:
This group currently has no users.
In backend I can see 15 users.
EDIT:
After refresh there was no change.
After logout and login back there were all 15 members back!
EDIT:
it seems, this was a singular problem.
I made the same in 4 other groups, there were no such problems.
I don't know why this happened. sorry!
