My Guild got deleted

Sometimes it can happen that Guilds, with no players in them, get deleted.
In order for this to happen, two requirements have to be met:

1. You are the only member of the Guild

2. You are inactive for more than 15 days.

You will be kicked from your guild, if you are inactive for more than two weeks. Since Guilds cannot be left without any players in them, they get deleted automatically.
