UK 4 server crash roll-backs

Hey there. So the roll-backs on this server has been going on for about 2 weeks if im not mistaken. Does anyone know what causes them? Kinda annoying knowing that everything you gathered or progressed with your house goes down the drain, and you can’t even play because you can’t say when the rollback will trigger again (sometimes the server can go 2 or 3 days without any rollbacks, but today i had like 4 or 5 of them, every one of them placing me in the same place i was this morning). Anything you know about these server crash roll-backs would be appreciated, thanks!
