Because a server I admin is a casual PVE, low stress, build and level server with a little storyline fun sometimes… We’ve turned the decay and abandonment off and regulate it manually. If a player is gone for 21+ days without showing a reset of the decay on their buildings and has not been seen on the server, we delete their buildings and structures to make room for new players to our server to build.
A MUCH better way would be to see a list of who logged into the server and when. This would work even as a separate app… anything that would help to do manual clean up on the server and be fair for the players.
