Sometimes items are reset to a previous version when switching servers

[Deleted user]

I'm not sure how to explain this, but sometimes when moving from server A to server B and back to A, the items will revert to an earlier version on the reconnection to A.

Maybe some timing issue? Do this only happen when we move A->B->A quickly?

If server B (or the database) is loaded, it is possible that the player will join A before B has finished writing the changes to the database. If not, try to find a way to replicate the problem and inspect the database before, during and after the server move and see what's going on.
