well, i do use enderchest to link my overworld rm factory to my End base and some other guys bases too, so they can get some free rm
but the chest is never overfilled, it's way too slow for that, and people keep taking the rm from it
anyway, that's true enderchests arent considered like other chests, everyone can access your enderchest, impossible to lwc
if it can be related to the bug crashing the server, right before it crash, i did make a new copy of my enderchest, destroyed it to get in my inventory, teleported from End to Overworld in someone house to place it down, it crashed when i was about to give the chest to him
