I'm using this mod to sort all of the creative inventory, so I make long lists of items/blocks that get sorted in the order I write them in. Some mod's items don't get sorted immediately though, and only go to the correct position after I update the config file (using an in-game config mod), which is a bit annoying as I am trying to make the menu as organized as possible. After a game restart they get reset back to their original position. Here are a couple of screenshots to demonstrate.

This may somehow be related to issue #8 even though that was fixed.

I have just noticed that it looks like the problem is caused by the configuration loading too early before all items are registered, as seen in "latest.log":

This does not occur after the configuration file is reloaded.

It should be fixed since version 2.1.0. If it continues, please reopen this issue.
