Maybe that was the culprit?
I absolutely would suspect rotator (and other equipment) attachment to the OTA before I would suspect rain or ground movement shifting the pier 4-6 degrees.

For peace of mind, I recommend pressing a level against the pier on two sides to determine if it is plumb or not.
