I was hoping they'd fix the cogwheel issue with the server restart this morning, but I'm still locking up at the Headless Horseman event. I put together an addon that will turn off your tooltips when you enter the Scarlet Monastery. If you're having the same issue in battlegrounds, you can also have it automatically turn off tool tips in there.
Check it out and save yourself from the constant pumpkin crashes:
