Update v0.8.5000a — Grey Hack Steam update #17135

Changelog - Fixed crash when synchronizing certain changes in the client when there was more than one player connected to the same computer. - Fixed crash when using computer.close_program if the script had already ended for other reasons just before completing the method call, potentially causing unexpected behavior. - Fixed regression bug that could leave a player offline in a corrupt state while their instance was being deleted, causing unexpected behavior in the actions of other players until the next server restart. - Temporarily reverted previous server update about old process list to persist after restarting the server, as it caused problems with other elements such as rshells. - Fixed regression bug that could cause the game server to stop accepting new login connections.
