[FIXED] Admin leaves group making a group without any admin?

[meme]

My username is meme.

I'm the only admin of a group. I'm leaving the group now. I enter my username (meme) in the "Leave and reassign group for" prompt and pressed the button Leave Group.

Now I'm no longer a member of the group. But I got an alert saying "
meme assigned you to be owner of the group "! When I visit the group, I confirm I need to join the group in order to be a member. And viewing the members info, I'm just an ordinary member but not a "owner"! I cannot promote myself or other members. And there's no admin.

So I assume this is a serious bug.

Now it prevents you reassign yourself in same group.
