Hey, I actually reloaded the choice after seeing this reply, picked Lily first and then talked to Mallory, but once the Mallory call ends I get the same error.
Don't worry about such mistakes haha, part of the reason I like to play WIPs is to find and report such things, so future players can have a smoother experience - it's rewarding on its own way!
I downloaded the game this morning, did you upload the fixed version just today? If you haven't imo you should, or at least add the patch as a downloadable file so players can patch the game.
