If u name an aircraft while it is an item, place it and then break it, its name resets to the original name
Example: Named quarcopter as 123 I place it, it become entity, then u break it, the item is dropped and its name was reseted to quarcopter again. But if you named any weapon or upgrade and equipped in the aircraft, even after breaking the aircraft and it becaming entity and item multiple times the upgrades and weapons keep the name modified by the anvil.

It's not a issue, it is just a sugestion, but I don't know how to mark the issue as "Suggestion" or "Enhancement"
