I can feel that you're getting closer.  :)

I hope you don't feel offended, but when I see that my problem has some logical nature, I stop the thing and approach it on the next day or so, after sleeping some time. There are days where you don't see or get a thing although it's clearly there. Next day, fresh eyes and mind, easy to catch.

If the problem is on the technical side though, I blame the devs.  :D
