Shuffled inventory on disconnect

[Piggered]

If a player reconnects after their inventory has been opened using the plugin, their inventory will shuffle. After reconnecting, the target will:

• Have their armor worn in upside-down, specifically;

  • Helmet will be worn on the boots slot;
  • Chestplate will be worn on the leggings slot;
  • Leggings will be worn on the chestplate slot;
  • Boots will be worn on the helmet slot;

• Have their inventory be shifted 1 row up, specifically;

  • The 1st row of inventory will be shifted to the hotbar
  • The 2nd row of inventory will be shifted to the 1st row
  • The 3rd row of inventory will be shifted to the 2nd row
  • The hotbar will be shifted to the 3rd row of inventory

• Have their off-hand slot unaffected (normal behavior).

No error is outputted in the console.

Tested on Spigot version 1.14.3-R0.1-SNAPSHOT with OpenInv 4.0.3.

Thanks, the images are particularly useful. No one had provided much information before and I hadn't made the time to go do it myself.
