Measure corruption on editing, score and part miscommunication

I'm not quite sure what is causing it, but on the most recent update scores and parts are not communicating all of the time. It seems like a random amount gets through, and this includes measures, time signatures, dynamics, and other general engraving. Because there literally are not as many measures in my parts as there are in the score, the entire file is pretty much unusable past a certain point. This seems to only happen when reediting measures that already have note values in them. Another oddity I've noticed is that quite frequently now, upon changing a preexisting note to a different note length, MuseScore doesn't update that note to fit the measure, but simply adds whatever note length you want to the measure. While this doesn't affect the visual engraving of whatever you just changed somehow, it means that the MIDI for that part is now behind everyone else. As well as this, any measures are considered "corrupt" because it contains too many notes for whatever the given time signature is. None of this was prevalent at all in previous updates, so I hope this is a relatively quick fix. However this has destroyed two large scale projects of mine, and even pasting in or fully renotating in a brand new score has the exact same issues. This issue makes the current build of MuseScore near completely unusable, particularly when either working with parts or odd time signatures.
