I'm not sure if you're understanding me, but I was using 1.1.2 of this mod, upgraded to 1.2.0, and Quick Reply stopped working. I did this as a controlled test, because I was aware of the Quick Reply problem others were having. The only thing that was upgraded was this hack.
Now if you mean to say that the integration hack has outdated code that is conflicting with the 1.2.0 update of this hack, then so be it. Just please realize that from my POV that *THIS* mod is what directly caused Quick Reply to stop working, as I have no understanding of all of your code, so telling me that I'm "technically posting in the wrong thread" is a little unfair.
Anyway, now that you've acknowledged the problem, I hope you can find the problem (in whichever hack it may be)
