Hi,
We are currently playing on multiplayer on a dedicated server "LOFT".
Since the 5th et 6th patch everything like crafting, building, opening/locking with code lock and moving things takes minimum 10x times to appear on screen and be done.
Most of the time moving, unlocking/locking and/or building something takes 5min minimum to appear on screen. Unlocking/locking with code lock is insanely long compared to other old patches.
This is def not because of the server.
I don't see other related bug report but I know other people are experiencing it too in my server and other serv too.
