If you try to rotate map, some moving entities (func_doors, func_rotating for instance) aren't rotated with the level. It's fixable manually for func_rotating by swapping X and Y axis flag, and if the level is rotated 180° by inverting the angle (from 43 to -43 for instance).
I had less luck with func_doors, probably because it says angles is not supported.
