So I've been running into this problem lately; certain UTAUloids (so far it's happened with Neko Kanochi and Momo Momone) won't work in USTs unless that UST is placed in their voice folder. Attempting to select that UTAU and play the song if it isn't in their voice folder results in the program acting like the UTAU's sounds don't exist. Is this normal? If not, does anyone know what the problem is or how to fix it?
