Changes to turn block?

So I have a merge cube space with a planet covering the cube.

I had coblocks set up and the Planet would spin on it’s axis using the turn block

turn “Planet” Clockwise by 360degrees in 15 secs

This had the desired effect until I came to revisit my space today and now the planet rotates around a point rather than on its axis?

However another space using the same code still has planets rotating on their axis correctly?

Space that works https://cospac.es/3oD4 (ignore Saturn)

Space that has issues https://cospac.es/NknX

Any suggestions?
