so my friend join my server and he worried sayed "where are my items" i make a copy of the nbt file (the one that contains player info like inventory and the health bar) the inventory was empty i think this its related to the fact that the server crashed so it could happen at the same time as the bug i reported (about the chunks being broken) but some how i dindt lost my items or armor now we are thinking on make in a new world with the same seed

but the damage its done and now we are debaiting if we give up or keep the our

for me i can make a world with the same seed and move inventories our i would make that but because the cause and the possible fix its unknow i prefer dont mind that for now
Have a good day
