Since Update 1.9, a small but serious bug has infiltrated the game. I'm not sure how many have noticed, but if you're creating levels, you might find your positioning of objects may be falling in and out of sync with the music. And same with regular levels.

On the first attempt, there are no problems and the music remains synced properly as usual. However, if you reattempt after crashing, the level will play off slightly ahead of the music cues. It's hard to tell whether the music is delayed, or the cube respawns a short distance ahead (of where it should normally flash in).

I'm going to make the assumption this is not a local issue and everyone else is experiencing the same thing (whether they're actively aware of it or not). This is critical in terms of properly designing levels, and for that reason I believe it is worth alerting RobTop so he can submit a patch more sooner than having to wait for Update 2.0.
