When I download my world now, the world is up to date and fine. The problem is that (what i would assume the playerdata folder) my character doesn't have the items I had when I turned off the server and not in the same location when it was on. I turned on the server and both the world and player data is up to date, but when i download it the player data is outdated
I've noticed that there is two player-data files for each person who have been playing on the server recently, but at the end of one of them it says ".dat_old"
I played on two separate save files of the world, one of the deleting the ".dat_old" files, and the other deleting the non -.dat_old files, and i was still loading up with my old items at the same old location
TL:DR Downloading world saves the current chunks, but not current player data
