Ok so, long story short, i just logged in the new server for the first time and did the normal stuff, registered, went to my base and i realised something
so before the transfer we were told to store all our items in a chest, including the enderchest and /chest items.
And i did it (duh). But when i joined the bungee servers i had all my items in my inventory, my armour, gear etc. My /chest was empty but my enderchest had my stuff in it. So basically my inventory and enderchest got duplicated. The interesting thing is tho, the contents of my echest / invertory were actually outdated. There was a pair of elytra for example that i gifted to someone some time ago. So it was like a rollback i guess? idk lol im just sayin i got my stuff duplicated
