ok, definitely there was a 2nd level, could custom import break it?

The only thing I can think of is some custom imports? Anyway maybe you can have a look and spot something?

I dont think so, i have the 10 minutes autosave option and the thing that was done was couple days old already.

Hi,
Have an issue with my plan.
It used to have 2 floors added but now when I come back to it it only has 1 level, 2nd level has gone.
Any chance to recover that?
I'm using a paid version on Mac if that makes any difference?
