B# and Cb octave change
After discussing this topic in the forum, seems it's definitely a bug.
OS: macOS Mojave (10.14),
MuseScore version (64-bit): 220.127.116.1125,
When inserting a B# or a Cb into a score, Musescore names the note with the wrong octave.
e.g. a sharpened B3 becomes a B#4, and a lowered C5 becomes a Cb4.
Look at the status bar (see attached screenshots)
That is reflected in the exported musicXML file too (that's the reason I noticed this issue).
