Our primary goal is to maintain the cleanness on the server.
Some players start ambitious projects on colossal buildings and don't have enough patience to finish them.
Or some quit playing for some reason, leaving extensive lands unattended.
For these reasons, there's Autoclean mechanism which is started once a month and checks all players and their lands.
If a player didn't play for a month (last login date is taken into account), then all his lands become free (like have been handed over to the server).
To protect his lands during a planned absence (like vacation), a player has to notify the server using the command:
The same subsequent command cancels the vacation.
The vacation lasts for 1 month per year maximum.
