Spawnable items are all missing - not deleted just different

I’ve made a blunder, added a Niagara VFX while the simulation was on.
All my spawnable metahumans and cameras all disappeared from the scene. The data is there, for the MetaHumans and Cameras, but if I resign actors, the animation will break the character mesh.
All the icons have a different icon, as if UE5 is no longer recognizing the items.

Does anyone know what the hell just happened and how do I fix it, without going the manual way of copying data to new actors (which will be the fix probably)

They cant be converted to possessable, they are missing from the outliner, and I can’t assign a new actor to them.
