This actually goes back to 2.1 if not earlier, but was first reported against 2.3.2 in https://musescore.org/en/node/276281

Steps to reproduce:

1) New Score, Grand Staff, 4/4
2) Add local 1/2/8 time signature (Ctrl+drag) to top staff only
3) Enter 5 C 4 C four times to fill measure
4) Select last quarter note C (on beat 10 of 12)
5) Press "."

Result: corruption

You can similarly get corruption with a quarter note on beat 9 if you use "W" or "6" to turn it into a half note, so the issue is not specific to the dot command - it's general to any duration change.

It's not any duration change, though, some seem to work OK.

The time signatures are also not significant. I ran into the same thing in 3.0 using 6/4 with cut time as the local time signature.

No doubt!

BTW, while you get corruption changing a quarter note on beat 9 to a half in my example, or one on beat 8, it works fine on beat 7. The corruption seems to have something to do with approaching the end of the measure.

In testing in version 2.3.2, anytime the note reaches or crosses the end of the measure, the corruption occurs. I put 3 eighth notes starting on beat 10 of the 12/8 measure. Every time I made the note long enough to reach or cross the end of the measure, it resulted in corruptions.
