One lyric went "ki" and then "me".
She had "ki" in her voicebank, but ACT2 is still W.I.P so she doesn't have "me" yet.
When she sang, she hit "ki" (sang it right) and then when she hit "me" right after, it repeated as "ki".
This never happened before. So I uninstalled UTAU, and redownloaded the newest one.
And the same thing happened, with or without the UST/VSQ/MIDI.
Anyone else getting this?
