I have an question.

If i have 5 world and 3 of them have the same inventorie
Example:
World 1: A
World 2: A
World 3: A
World 4: B
World 5: B

And i remove MultiInv which inventorie world will he use as default? (Wich world's wil lose ther inventorie?)

"Your current inventory is saved in the players folder of your default world as defined in your server.properties folder. Now for the nitty gritty:

MultiInv keeps all other inventories in separate folders inside the "groups" folder."

... So look in your server.properties and check what world is set as the default world :)
