The server worked completely fine yesterday. I did not tamper with anything, started the server today, and it now crashes on startup.
I have attempted to research this problem and I cannot find the exact same problem online.
Could you please send me some examples. I'm having a rough time trying to get it working.
I don't know why but I don't have: PlayerInventory#save(ListNBT) nor PlayerInventory#load(ListNBT)
But instead: #write(CompoundNBT) and #read(CompoundNBT)
