Inventory doesn't save/load

[McianPlays]

When I put an item in my inventory, disconnect, then rejoin, that item doesn't show up in my hotbar!

I've gone through the config and worlds yml files but nothing seems to be out of the ordinary.

Is there something I'm doing wrong?

Thanks.

I am unsure which version of minecraft your server is using, but our load-data-on-join setting could help with this issue if you use 1.9.2 or newer.

Also just wanted to mention that you put 1 second for save-interval, which could slow down server performance (default is 300 seconds). ;)
