When removing crates from an expanded crate rack inside a vehicle, the player must move the crates out of the crate rack and into the vehicle inventory first before unloading them.
If the crates are unloaded from an expanded crate rack to the ground directly they become ghosted. The crates appear to be on the ground, but they are actually still in the crate rack.

This then causes a crate rack that seems empty to not be able to be taken out of a vehicle, and a crate rack to be able to hold less than normal because it already has invisible crates inside it.

If the crate rack is empty but weighs more than 6.5kg, it has ghosted crates in it.

There are multiple ways to fix the issue:

• If all crates can be located, move them back into the rack they were taken out of, then unload them properly as per the first paragraph at the top of this page.
• A GM can use #loadItem WurmID to load the crates into inventory if they can't be found, then drop them and load them into the vehicle with the bugged crate rack.
• Use #loadItem to pull the crate rack from the vehicle, then destroy it. The crates will drop on the ground and normalized. Note: Any ghosted crates left after destroying the crate rack will be null crates that no longer exist, and will be cleared on server reset.
