Invalid target error on random casts: irradiated undercoat MC

Per the two threads that I’m going to link, I’ve been having trouble with “invalid target errors” when I try to start an attack, the attack tries to land, or I cast a spell on myself. This has resulted in spells not casting at all, spells casting but not landing, and spells working as expected despite the error.

I renamed cache, interface, and WTF, retested without addons, and still got the error. I tried the scan and repair tool, but still got the error. So I took off all of my gear and retested after putting each piece back on. The error was encountered while wearing Irradiated Undercoat but not when it was removed. I tested back and forth a few times.

Per this second thread, another person was having the same problem and removing the Irradiated Undercoat fixed it for them as well.

In my case, the casts after putting on the Irradiate Undercoat were all successful until I got mind controlled. After mind control dropped, the error was permanent (albeit intermittent). The second post has less detailed information about when the problem started.

im afraid that it cant all be down to gear i don’t have irradiated undercoat or any engineer gear on, I am a BM hunter and feel it may be more of a class issue. I logged of last night and was having no issues and logged on this morning and every mob i try to attack errors with invalid target. the really strange thing is if i right click with mouse auto attack works but i cannot use any hunter skills to attack monsters , really frustrating to have this occur

and like magic , log a me too issue and find the solution to invalid target on a youtube post. All i had to do was to hit the Alt key to restore normality in my life, i should have just looked a little harder i guess , but hope this info helps if you didn’t already know

i am getting this problem is ther a fix i have uninstall wow and still getting the problem im not wearing that piece of gear either
