Re: Columns change the height on the platform
I tested this and found the same thing you did. If you save the lot to your Library (or Gallery), then the base of the columns will relocate to the top of the platform rather than remain where they were originally placed. I did find that after placing the lot, you can get them back to how they were originally place by moving them. See the attached pic.
I'm not sure if this is bug or just another quirk of the build system but I have to agree with you. The column bases should not move just because you save the lot to your LIbrary or to the Gallery. They should remain in the location they were originally placed.
Hope this helps.
