Calab, as lexor stated, yes. This has to do with the nature of crates. Crates don't store the actual items. Indeed, a crate is nothing more than an item that has a quantity and a reference to what item type it contains. This leads to crated entities losing their customs. Those items actually cease to exist and are recreated once removed from their crate. The reason production entities can have customs while in crates is because the crate itself stores a reference to the custom that needs to be applied to all of the entities inside. It'd be nice if crates would maintain the same custom if all entities package into the crates had the same custom, but unfortunately that'd probably be extremely inefficient and also would still lead to customs disappearing when you crated entities with different customs.
