Build float height reduced to 2 clicks

Hey all. I posted this after last PTR's changes and it looks like the bug is still present:
https://playnightingale.ideas.aha.io/ideas/RRBUG-I-1339

I've noticed that I am no longer able to free-build in the air. A couple patches back, I was able to raise items up with R+mousewheel a relatively infinite height. In other words, I made a bunch of stuff float. The effects were amazing and I loved it!

If I try the same items with the same method now, the item will only raise up 2 clicks of the mousewheel before the wireframe turns red. This limits my ability to complete the glorious magickian school of Logwarts.

Hopefully this is but a fleeting bug and not working as intended.

I've attached a couple screenshots of trying to float a candle above a shelf in PTR. One shows green at 2 clicks up, and red at 3 clicks. The last pic is my glorious magickian school of Logwarts with a gazillion floating candles. I love it so much, and I'm absolutely crushed that I can't continue with building it. :(

Also, trying to build on a shelf now and then removing the shelf will drop anything that the shelf was supporting. That did not happen with the initial release that allowed building without supports.
