New save/load system is in effect and are now both client-side and server side saved. You should be able to swap servers again.
In the event your save doesn't load onto server from client-side it should load one from the server you are playing on if any is located.
If you are moving to a new server and the save doesn't load, I recommend trying a relog.
Will see how well this new system works in the coming days but until then,
Regular game updates will resume again.
