In the Patch notes today it mentions that the composer UI no longer off sets notes on the UI when changing BPM or zoom levels and new 32/64 timing for notes. This however has had two side effects. 

It has not fixed existing songs which were way off timing due to the timing of the notes being moved on the UI every time you save. and now that the 32/64 timing has been added, those existing bugged songs now see the slight off timing on the UI as actual timing in the song rather than it jsut being a display bug on the UI.

This means I have to go through all my existing songs and fix them ALL, and the songs which have already been uploaded in the past and cannot be edited/fixed (beucause theyre in the online album) are now all broken.
