Found another Bug, which i knew about for a While now, but never took the Time to clearly test.
 Now i tested it, here is the Result/ Description of the Bug.
 Test was done on Firmware 6.0, but older Firmware had the Same Basic Problem, didnt test that however, if it behaves exactly the Same.
 So, as i used 60fps or some random lower Framerates occasionally, i noticed, that on 60fps, once you set the Framerate, the Exposure Slider will not work as intended anymore. The Thumbwheel still works, as does the Exposure Slider itself, but once you try to get to longer Exposure Times/ bigger Shutter angles, the UI starts to Glitch out. You can set maximum Exposure Time by dragging the Slider on the Touchscreen all the way up with your finger, but you will not be able to increase the Shutter angle With the Thumbwheel beyond a certain point. Once you are At Maximum Exposure however, you can use the Thumbwheel to go back down in exposure again, but not back up after that. Will still get stuck at the same Point, if you try to get back up to maximum exposure again.
 As i knew that this was showing up on 60fps, and that it got way worse on even lower framerates, but still working fine at 100fps and seemingly random, i started my testing there.
 90fps Still worked fine, at 80fps it was already showing up, so i started my testing there, and tested every whole Number Framerate it would let me set (tried 1fps, but it wouldnt even let me set that, but just freaks out and set 1kfps, so lowest i did was 2fps).
 Now, i know that everything below 50fps is very impractical to use on this camera, and also recently learned that 60fps is supposed to be the lowest officially supported Framerate by Krontech, but as i noticed that there is some pattern to how it behaves, i included it in my test here anyways, as it might provide useful information in trying to figure out what is going on and help solve the Issue.
 Tested every Whole Number of Framerate from 90 to 2.
 Below follows a list with first the Framerate(-s) and the maximum Shutter angle i was able to set with the Thumbwheel at that framerate(-s).
 Test was done on an Chronos 2.1 at Full Resolution, 0db Gain.
