Model duplication when changing worlds

Issue applicable to Model Engine 3 and 4

It seems that for some reason, when a player disconnects or changes world the model loses the connection to your internal instances for the actual entities, this only happens if the model is using a bukkit entity as defaultand if the model is not on "world", "world_nether", "world_the_end" (The default ones)

Did some debugging on the chat to see instances and making sure I'm calling the correct ModelEngine objects (Based on the hashcode)

I'm using MultiverseCore for the worlds

Code:

ArmorStand entity = (ArmorStand) loc.getWorld().spawnEntity(loc, EntityType.ARMOR_STAND);

entity.setVisible(false);
entity.setGravity(false);
entity.teleport(loc);

this.modeledEntity = ModelEngine.getApi().createModeledEntity(entity);

this.modeledEntity.addModel(this.activeModel, false);

this.modeledEntity.setRenderRadius(this.crate.getPlugin().getConfiguration().getCratesRenderRadius());

Note: "ModelEngine.getApi()" is a custom implementation for multi-version support. This problem was already happen before and the system itself is not a problem
