Yesterday I made up a song that utilized a 200% tempo.
Today when I opened it up to resume work it had reset itself to 100%.
I fixed it, and listened to a few measures before deciding I was going to work on something else instead.
The next song I opened started playing at 200% tempo.

Is this behavior a result of something I'm doing or not doing? It's pretty much impossible to forget to save things, if you do forget and go to exit or open another song I get a pop up.

I usually save song projects in their own folders, especially if I am going to be adding tracks from Reaper. But last night I was just buzzing through a bunch of stuff and made up three or four songs in a general folder.
