Lost entire first floor

[murek]

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?

Didn't you experience any crash or some issue that would have made the program quit without saving?

[murek]

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

I want to propose that you send [url=mailto:[email protected]]me[/url] your file, but I have very little hope. There's no reason why a level would disappear without the user request to delete it, and it can't be an error in the written file (otherwise the whole file would be unreadable).

Could it simply be hidden?

Or did you change the height and tiped in a digit more than it should be so the floor is now much higher above than you want it to be?

[murek]

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

There's no second level / floor in your SH3D file. As soon as there's more than one level, some tabs appear at the top of the plan, as in the following image.

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

[Puybaret]

I never heard about a level disappearing from the tabs and don’t see how it could be because of a custom import.
