Generating the same particle twice overrides the existing layer but with broken orientations

[brisvag]

Passing layer data tuples is causing this override. What exactly causes the broken orientations, I don't know yet...

[brisvag]

It's weirder: even changing visibility of the particle picks soemhow resets/affects the orientations. Seems like they get multiplied maybe, isntead of replaced.

Fixed orientation issue, but now we need to no override layers if coming from separate origin layers.
