Hosting my own private server through the xbox nitrado servers, occasionally lag spikes which affect every player on the server at the same time will cause any vehicles driving to completely lose control and wreck. Slamming the breaks will not always save you and having this be a constant thing makes a lot of players quit the game. (I only drive below 60 because of this but it still aint safe)
Items stored by players are also frequently stuck in containers. (I think it happens more often if your server hasnt restarted in a while) this is fixed by restarting the server but having it happen so frequently has made containers obsolete unless you have the power to restart the server yourself. (I have to restart it every 20mins pretty much)
A bandaid fix for the cars temporarily I guess could be just to disable damage temporarily on lag spikes or freeze the cars position? Anything is better than having to constantly fix the same frickin car over and over from server lag.
