What steps will reproduce the problem?

Assume there are 2 worlds A & B with their inventories different (Multiverse Inventories), also assume that world A is the spawn world. in the config file everything is default except for, ForceSpawnLocOnJoinEnabled: true & teleportUnAuthedToSpawn: true

When a player logs out in world B (Skyblock, plugin used : IslandWorld) & logs back in the 1st slot they have is "invisible", however after teleporting to world A and back to world B it reappears. Also sometimes the inventory is just moved to the spawn world & World B inv is empty

What is the expected output? What do you see instead?

Inventories should stay where they were on logout, they move @ times
