A player on my server found that he couldn't connect to the elements, but when he tried to re-enter the server, he found that all his previous elements had disappeared,The server data synchronization plugin I am using is PlayerDatasql,But this plugin cannot synchronize elements.Perhaps the data of your mod does not exist in the playerdata.
This is a screenshot of the player before and after entering the server
