To use custom data on an Entity, you need to call patchEntity(ent) on it at least once. This will respawn the entity and return the new Entity. Since people might not expect this to happen, the getNbtData method doesn't do it by itself like with Tiles.
Yea that method only does anything if needed, so you can call it however often you want/anytime before using custom nbt. With riding entities... Eh don't? Bestcase the entity gets ejected, worstcase it vanishes or gets corrupted because it's mount is gone. If you plan to have custom nbt and using mounting, patch the Entity before putting anything on it(Best case just spawn and patch it in one line of code).
Alright thanks,
is it okay if I call it each time before I am about to set the metadata?
If the entity is riding something will the mount eject, as well as are there any other implications?
