The new version of the plugin that manage game mode and inventories are breaking the way enderchests store data. There is a high risk that when the next version comes out, all ender chest inventories will be wiped.
So make sure that you do not keep inventories in enderchests when you log out. Once the final version of that plugin is out I will upgrade and there is a chance that all your stuff in the enderchests will be gone. You have been warned.
Is this still an issue?
This might be an issue once the new version of the plugin is released. Do not use the chests as longterm storage.
so glad i just randomly read this
