Sounds to me like "bugs". Sometimes the word "flaky" is used to describpe the program.

In the past several days I have been working on an issue with a VSTi which has caused my DAW to be "flaky" more in the last two days then in the last two years. I mean my DAW is generally rock solid, it never locks up or freezes needing a reboot, unitil the past two days when I have had to do it over a dozen times. I have both the DAW and VSTi developer looking at the current compatibility problem.

So what does that have to do with your problem, I guess nothing other than I feel for ya. These DAW applications are a joy when they work and a real pain when not. I think RB does need some fixes in areas, hope the new version will address your current problems.
