This is an extremely annoying issue I keep running into since FL Studio 12 while copying and pasting selected notes or parts of a playlist.
When pasting the copied selection, it is applied off-center so it will become off-sync. Every time this happens you have to zoom-in and move the selection slightly to the left again to fix it.
I never had this problem in FL 11 and it's quite frustrating because it breaks your workflow constantly when trying things out.
