Here's the typo I found, it's the part where the player picks "How did you find out about this party?"
And since you have mentioned making other games I can check them out in my spare time and review them also. Don't sweat it trying to make a good mystery, one advice I can give that I've learnt after playing the DGS Duology is to trick the mind of the players. Make it subtle and have the player think of the obvious answer, then when new information is discovered it could change their minds in a new light.
Good luck on your future projects!
