I feared this wouldn't fix it, would have surprised me somehow anyways but everybody gets a lucky shot at times

I just don't seem to see the problem yet, I even have setup a "fake/simulated" L3++ for my script that hands out the json reply from you and guess what: works nicely.
Need some sleep first and will look over it tomorrow again, right now I am out of ideas and its hard to fix a problem I don't see and can't reproduce.
Though thanks for your support and input so far, that's motivating.
