Changing measure duration creates corrupt score
Under certain circumstances modifying the actual duration of measures in Measure|Properties creates a file that MuseScore reports as corrupted when opening. Perhaps on changing 2 adjacent measures?
See attached image.
Running on MuseScore 2.1.0 unstable (compiled locally today) on Chromebook/Crouton/UbuntuTrusty, however have seen the same behavior on Windows 7 with MS 2.0.0 and earlier versions.
Steps to reproduce:
1) Create new file from template. Template is provided as attachment Church.mscz.
2) Set to 3/4 time.
3) Enter some music as shown in attachment "corrupt.png"
4) At measure 9, stop at note entry mode and change actual duration to 1 / 4
5) Enter note in measure 9
6) At measure 10, stop and change actual duration to 7/4.
7) Continue entering notes into measures 10 and 11.
8) Save file, exit the file, reopen the file, MuseScore reports corruption in measure 10.
Corrupted file is attached as 564c.mscz

Maybe a similar problem here https://musescore.com/user/3541/scores/864346
It's the drum track at 2/4 to 4/4 the voices split with a half note length. When trying to re-arrange the tracks I get an upload error https://musescore.com/user/3541/scores/883606
Hope to find a solution soon
I have one correction to what I posted earlier. I didn't actually use the Church.mscz as a template file. I actually used the template for "single instrument" that is provided with MuseScore.
I can reproduce the corruption.
The key seems to be the combination of the 7/4 actual duration and an empty measure, but the corruption is only detected if the original time signature is 3/4 rather than 4/4 (not sure about other time signatures).
I filed an issue: #61476: Corruption reading empty measure with 7/4 actual duration
Any solution to this issue yet? Kind of makes the program useless

Yes, it is fixed in the recent nightly builds

Sorry - where/how do I find the "nightly builds"

I wouldn't advise to use nightly builds for anything serious. It's better to stick with 2.0.1 really. If you think that the inability to change the actual duration of a measure makes MuseScore useless, maybe there is another way to do what you want? The problem only occurs if the measure is more than 4/4 and starts with a whole rest. Changing the whole measure rest to a quarter note rest is enough to work around the problem.
