I assume when you updated your server you entered a command along the lines of , correct? I haven't heard of it happening on any other servers, and the one I run has been fine, so I would assume it is only a problem with your server, not the mod.

It sounds similar to when the ids (not uuids, please do some research to learn the difference) get messed up, but different in that it only seems to affect stuff from before the update as opposed to everything on the server.

I can't say much more without knowing more information about your server. What jar are you using and what version (forge, cauldron, etc.) Are you using any other mods? Can you post all logs from when you updated the server to when you noticed the problem (Preferrably zip them all together and upload them to mediafire, or something similar. DON'T make a wall of text).
