[URGENT] Player Files not saving on logout

Alright everyone, I am in desperate need for help. When my players log out then log back in, the world stays the same but their location and inventories revert a certain time, probably last time I did /save-all. This is a problem because players can duplicate their items by placing their items in chests and logging out then back in. I have the server whitelisted so I will need a fast and working response.

Thank you Bukkit Community.

Why are you bumping other people threads? It is up to the thread creator to do so.

 

Joshdude7 This is a very old problem which occurred frequently back before Notch changed how inventories were handled (back in the days when you could hexedit). Could you list your plugins and your server's specs?
