Well, you'll see if it imports correctly, mostly it should work. Unwinding repeats is useful also for phrase/section markers and because real songs tend to do variations. Fixing multiple identical sections by copy-pasting is also easy so there's no huge reason to keep them.
I really don't remeber, it might even be corrupting EOF or maybe that was another bug. Anyway it's better to resave as GP4/GP5 to avoid issues. ok - thanks! yeah i normally would copy-paste the sections but I somehow just looked at the gp-file in GPA and there the repeats were not visible... so I started syncing and realized later that there were those repeats in the file.
Well - I will see...
Repeats are not a problem for GPA, it always unwinds them internally and you can replace them any time.
