Adding  to your JVM arguments will allow you to bypass the   although I'm not sure if it will work for cauldron. When you update the server. You should delete the current LOTR jar from your mods folder and replace it with the new one. Then start the server and any changed item ids should be automatically remapped to the new ones, so that gondor blocks don't turn into flowers. If that doesn't work then, I would guess that cauldron does something different in the update process. If you were to switch to forge for the update and then back to cauldron, would that ruin a bunch of stuff?
