Place few foundation blocks.
Try to place a wall section.
Try to rotating the wall section using the Right Trigger on controller.
Watch your character punch at the air, if not holding a weapon.
Go back into placing a wall section and rotate as normal.
This also occurs when placing workstations.
This is happening in all Testlive servers and solo-player (and Xbox).
This is very annoying when trying to place a lot of pieces and they seem to rotate on their own and then need to be manually rotated.
I added a link from a previous reporting of this problem on a thread that has since been locked.
