Yes. To be more precise:
I tried several golems after the latest patch. Tried placing them on Arena foundations, Stables foundations and Stables ceilings. I could not find a spot on the foundations where the golems could be placed. Stables ceilings worked, but not perfectly - I still needed to wiggle the golem around to make him able to be placed.
On bare ground (even uneven) I had considerably less problems.
