If a player is inactive for a certain amount of time, does the system automatically purge their base from the map?
We had a few bases of members that were inactive and their bases just disappeared.

If so, what is that time frame of inactivity before this happens?

Additionally, what happens to a guild if the inactive person is a guild leader and his base is purged? Does the system disband the guild or does the guild still exist without a leader?
If this is the case then there would be no one in the guild that is able to take control to promote or demote r4 positions, or have privileges that only the r5 has.
Thank you for any replies.
