yay! strangely for some time, i ended up uninstalling AT around september because i was diving deeper in music. and was inclined to look up on the progress... (which only .7.3 is on f-droid, but runs okay as far as i know...)
i was all prepared to continue and looked for my old save file on my external hard drive.... gone. so i get to not only eerience the updates, but also get to experience everything as it is intended.
