Player logout and groups

In 3.3.5 what is expected behaviour when a group member logs out? Is that group member supposed to be kicked/leave the group?

We recently had a 3 man group going, and every time someone logged out and in, they left the group and had to be re-invited. I just can’t remember if this was the behaviour in 3.3.5 or not, it seems wrong and very annoying, especially when in an instance.

if they logout voluntary is blizzlike being removed from group.

Ok, thanks for the reply
