Glitch number one:
Have you ever got blood of oceanus from sister pedro? Because I renember that I saw those big green beatles before petunia the angry. I knew that she will be shooting at me, so I prepared my ninja stars. Also I found beeping tom after killing the loomi (blue fox) boss.
Glitch number two:
Very weird glitch at that, mnemousyous forge or how is it called. The forge upon astraea's bastion. So you go there, put the sorceror's sapphire in the first slot and rusty dagger on the second (you don't need the regal sword, just place an item so it's not regal sword.) Now you clear the second item off and you will craft sorceror's sapphire with nothing. It should work.
