In Editor mode, if you have a saved beatmap, and try changing the Lead-in time in the Audio options, the beatmap won't ask you to save when you Test it, and does not save the change in Lead-in (you can see in Test mode that the map didn't change). Fortunately, you can "Save Beatmap" in the "File..." menu after adjusting the Lead-in and then Testing, since that way the map will be correctly saved.
Tested with the latest version a lot of times in different maps, and it seems a pretty solid (but quite small) bug.
I know it's kinda useless to report a bug that can be avoided by other means, but I guess that kind of thing can make osu better and better.
On a side note, I'm still having a lot of BPM desynch in the skin selection screen, mostly with maps with many resources like videos and custom sounds, but I haven't found anything to prove it yet. But I don't see why would my computer do that alone. It seems it's likely to happen with a lot of people. In my case, osu freezes for a moment, while loading the skins for that screen. Maybe that happens more often the more skins I have installed?
EDIT: Ok, now that I re-read, it looked a little confusing, but what I meant is that when you SAVE a map, THEN change the Lead-in time and THEN try testing it, it won't ask for saving like it does when you edit more important things like hitcircles and map difficulty.
