Details

I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.

Description
Fireworks with Flight:-2 in the inventory or ender chests are stored by MV-Inventories data as "power":254, which causes an exception to show up periodically, each time the player's MV-Inventories data file is accessed:

Steps to reproduce
Place a firework rocket with its NBT Flight set to a negative number (-2 fires the rocket immediately upon using) in your inventory or ender chest.

Expected behavior
When MV-Inventories is set up with different world groups and inventory/enderchest data is written to individual player files, this negative number is stored as a positive >127 number, which causes an exception as the plugin is not expecting values above 127.
