"already retired" bug still occuring with plugin-created armor stands

[Budderman18]

While the entity still does die, it still errors out, which is really only a big deal for the /kill command, since multiple entities won't work.

Do you have reproduction steps for this? I've gotten a bunch of reports but haven't been able to reliably reproduce it.

[Budderman18]

1. Using a plugin (that part is key, vanilla spawned ones are save), spawn an armor stand somewhere.
2. Kill that armor stand in any way, either /kill or destroying in Creative
3. Should throw the error, but still gets killed.

[kev626]

Can you provide a plugin that exhibits this behavior?
