Additional Notes

I can’t pin point the exact issue it happens at the most random times at gameplay but for the editor it happens when ending game. This does not happen on non physics map so it has to do the physics in an island. The game survive the disaster has very complex custom scheduling and physics processing there is max 25 physics objects and max 25 fake physics objects. I do not have physics objects > 50 like the warning in UEFN says so its way within limits. Problem has been happening for about 1-3 weeks thats the best I can pin point it, it happens after one of the recent updated during this times , before it worked normally so this isn’t an island issue becuase something in the past 1-3 weeks has caused this issue to happen constantly.
