Would it be possible to get a copy of changes to my BP view Dropbox ? Im trying to recreate way you solve this but I don’t understand how you are casting ? Would really appreciate 
I dont think for asteroid spawn max float range is being reached though because if you see in SolarSystemBPWorkwithArrayInternaly asteroids spawn, I agree that this wouldn’t work if last system bounds offset system worked but it currently doesn’t
In my new setup i lowered scales a bit, but can still change scale if needed, also another change with an observation
I noticed that If I add say 20000 alongside highfloorscale(which is systems size) to last system bounds then it will only add 20000 each time, not system bounds, so highfloorscale returns 0, this eliminates possibility that variables are too large.
it seems that any vars obtained from spawn actor solarsystemBP doesn’t save if it, but vars do save in solarsystemBP which are created from spawned actors ?
