Just tried the latest download
Don't have time to do a really good bug report, just reporting that it really messed up the score visually & I wasn't sure what happened. The bars in the 1st line were OK, maybe 1-8, then the next bar it showed was bar 24 (which I hadn't got to yet) all stretched out with some rests and random slur marks and notes. I thought maybe it had eaten all the other bars in between. This started after I started inserting horizontal spacers (Mac) luckily all the data was OK. I saved the score and opened with the previous 2.0.3 which I will be using from now until another rc comes out that doesn't do this.
