3/4 and 4/4 Time Conflicts
When creating a new score in Musescore 2.0, go to "Create a New Score" (you don't have to fill anything out), select "Treble Clef" under the "General" category, key signature and tempo does not matter. When entering time signature, make it 3/4 (pick up and number of measures does not matter). Then, change the instrument from piano to anything else. Add some notes in a few measures and at some point, switch a measure(s) to 4/4 time. Save the score and exit musescore. Now, reopen musescore and the newly made score. The whole score will be in 4/4; any measure with 3/4 still have the same amount of notes, but have an invisible rest (that can't be deleted) at the end of it. Trying to replace the invisible 4/4 with a 3/4 will cause musescore to crash. Copying and pasting the notes and time signature to a new score won't fix this.

I can't seem to reproduce. There is no MuseScore 2.0 yet, just a series of experimental prerelease builds. Which one specifically are you using (see Help / About)? Can you post the specific score you are having trouble with? Oerhaps it depends more on the exact notes you add, which measure you change to 4.4, etc.
This is in beta 2. Perhaps it's just my specific computer problem, but I did find a solution. Unfortunately, I cannot use the solution on my current score. The solution is to manually change the time to 3/4 after changing instruments but before adding notes or changing time signature again. Also, I use a Windows 7. As for notes, I used a variety from 32nd to duplets and had tempo changes with key changes as well. I'm typing this on my phone so I can't exactly show you the score nor do I know how to wit my computer.
One more thing, when I said computer, I meant laptop. It runs slower but let's me carry it to a local Starbucks and do some work while enjoying coffee. Maybe the problem is that my laptop simple runs slower and can't correctly process certain things. I honestly have no clue, which is why I'm a musician and not a technician.
To attach your score next time you are at your computer, click the "File attachments" link right below where you type your response, then Choose File and browse to your score.
Using a laptop shouldn't be a problem, BTW. That's all I've used for years.
Here is the score.
Well, something definitely seems off - there is not time signature at all (which can happen if you delete it), the measures all report via measure properties to be in 4/4, but they have only three beats.
I guess the question is, can you provide a series of steps to reproduce this problem when starting from a score that is *not* already messed up? Your original steps don't seem to do it.
I think I know how to recreate the problem. Do as the original steps say, but after making the score in 3/4, add the 3/4 time signature, and then switch instruments. From my memory, this was exactly what I did. It is reassuring that my problem is a legitimate problem and I don't sound crazy.
Sorry, I still can't reproduce. Did you manage to recreate the problem from scratch, or are you just trying to remember what you did before? I suspect there was more to it - something involving deleting a time signature or undoing adding it or inserting measures, for example.
Ideally, what we would want is a very detailed series of steps - saying which measure to add the time signature too, what measure to add notes to, etc - that you have tried out and can verify reproduces the problem for you every time you follow that series of steps.
