got it working again, but only when I align every single pivot for every single object and Y-up, does it work.
after this I simply changed the spawns pivot Z| to 45 degrees offset to the others, and my wheels are broken, pointing left. very strange, can only spawn facing south.
nothing I do to the object either rotating pivots=broken, rotate object = no rotational spawn.
even if I rotate them all at same time it breaks it, but when all facing south on blue Z pivot it works.
