VERSION V.018A BUG FIX:
Mega
This fix addresses the last comments, regarding the Music Quest and also Flowerbell Quest; and in addition another bug that I just located and that prevented to unlock Meteorite's house.
Thank you very much to those who have notified me about these problems. Hopefully there aren't more (fingers crossed!).
Please, let me know if the fix works, and especially if it doesn't work.
