David, and others.
I think I found the problem. I've been doing this all the time. To make things easier and more clear about what I'm doing when working with large-scale buildings with complicated geometry, I've been grouping and hiding the spaces as I wanted to draw other floors on the building.
In one of my attempts to recreate the building I grouped and hid the 1st and 2nd floor to create the 3rd floor but after creating the 3rd floor I had to leave and I didn't group the whole building this time and just saved them. When I came back and reopened the osm file, 1st and 2nd floors moved to the origin as in the original problem I mentioned but the 3rd floor stayed where I created and want it to be.
So then I recreated the building in the same order and this time I didn't group the spaces along the way. Tedious but wallah!!! The building stayed as I want it to be even after saving it as an osm file and reopened. Therefore, I think the culprit is when I group and explode, due to some programming or coding issue spaces don't explode properly. Meaning original positions (x,y,z) messes up when group, hide, unhide and explode or work inside a group.
As long as I don't group and explode or work inside a group, the building stays as I want it to be even after saving and reopening osm files.
I'm sure this is something that developers should look up and fix.
Cheers and you're welcome.
