[Solved] Calling LoadAssetAsync<GameObject> On a prefab is spawning objects into the scene that hav

addressables 1.7.5 unity 2019.3.1f1

I have a hugely complex prefab that contains many other prefabs maybe a thousand gameobjects all together and many mesh renderers and other assorted components

its an addressable

I call LoadAssetAsync<GameObject> on its addressable

Unity loses its mind

about 4 of the child objects of the addressable actually spawn into the scene the hierarchy shows them as greyed out (see imgur link)

unity logs errors like these

then unity editor crashes with a callstack like this. I flip my desk over and give up on addressables forever.

going back to 1.8.3 seems to have fixed this issue, unsure if I had maybe a cached object somewhere built with 1.8.3 (when I previously tried it) broke 1.7.5 even though I rebuilt data many times with 1.7.5
