I spent enough time and documentation on it. The bug is clear and intermittent, I am a developer myself and would not need more to understand the bug.
I did no pay regularly for this software to spend a lot of time reporting bugs BTW, so please feel free to format it yourself if you’d like.
Thank you for editing the bug title, to be clear and as mentioned at the end of my report, it does not happen frequenetly though, but when accumulated with other intermittent issues; it is still frustrating of course.
@TakashiWatanabe Interesting hypothesis, but I don’t think so because, when I selected the part in the end, it automatically would have deselected notes of the start part and one thing I am certain is that I was selecting and then looping on what was my current (ending) loop before the buggy transition and then i could have have eventually edited notes on the ending part, but they would have been deselected too as soon as I selected the starting part (double-checked that scenario too).
And what is also certain is that i did not select other notes from the starting part that was not playing, just clicking on that part itself then pressed p in the arrange window, then selection did change but not as I expected and also it was selecting the end of this starting part so it could not be the ending part notes?
The video does not show what happened before the bug, but what happened before was that I was looping in play mode on the last part and I remember i did edit notes from this part on the bottom track but as the video shows, it is far away from the new selected area.
Thanks for the idea though did not even know that this feature existed, it could have been that: the selection really looked like my C3 note there.
EDIT: I’ll mark it as a solution for that one in doubt because the selected area really matched the note and while I switched apps to capture a video it could have been de-selected, so giving the benefit of the doubt here
