Maybe I've done something wrong?
I downloaded the 0.9.0.1 server files.
I renamed server.properties to server.properties.bak
I renamed default.permissions to default.permissions.bak
I replaced these two files with the files from my 0.8.2.4
On first running the server I got this (its the ERROR ones that worried me)
Code
Now if I open a chest I loose anything in my inventory slots?
