Member can't return to alliance

We had a guy step out last night and now he can’t come back.
Usually we just wait 30mins and they can come back - has this changed?

Did he leave, or was he removed by a commander? If he was removed by a commander, there’s a longer wait to rejoin. I believe he has to wait 24 hours in that case.

Must’ve been that. Thanks Davy, he’s in now.
