Has anyone since this last patch experienced.......quirkiness with their action ranges?

I first noticed this yesterday when I was doing my weekly hunt, and kept getting the "target is out of range" error while I was on my tank, then noticed it A LOT in Qarn today.

Did some tests on my striking dummy, and in some cases when this happens, my casting distance is cut by more than half. But only sometimes. Logging out and logging back in seems to help for a little while.

This happening to anyone else? O.o
