I tested again now and I am still not able to reproduce this. Could you provide some more info:
- Browser and OS
- Steps to reproduce
- What exactly do you mean by destroys, nothing happens at all? Hide meanings works but quick answers doesn’t? Do you get any errors in console?
Yea Reviews plus is largely based on Quick Answers from what I could tell looking a the code.
Possibly my most popular script: Better Lesson Picker 
(I’ll rename it as well)
