Archimesh baseboard

Hello!

The archimesh baseboard seems to have an issue: The baseboard is not visible if the thickness is increased to a value >0. It doesn’t matter if you inverse the walls thickness. Can anyone confirm that?

Here would be my file I tried this out with.

Thanks!

Edit: Inside the room there is a modifier group. Playing with this modifier (so it is greater than -1) brings back the basboard with inversed walls.
