Left click to target. Right click to auto attack. You want to target the rock, not attack the rock. (I searched for your other posts to see what your issue was).

So while one could argue you were doing it wrong, I'd instead say that the bug is just that it lets you do the wrong thing and/or that when you auto attack the rock it doesn't give you a message explaining what's going on.

To answer the question you're technically asking, though, the closest I can recall was when the main quest got broken for a while (it involved a pipe in Mor Dhona). I don't recall exactly how long it was like that, but I feel like it was fixed in just a few days.
