Woah, great catch! I thought it'd be cool to be able to sign up for a trial as an NPC, but I haven't written a dedicated scene for that so I left it the same as the main character without realising that it would break. For now I'll just change it so when it's an NPC you still get the money and the effect, but it skips the part of cutscene that's meant of the player. A special scene for other characters would be cool though, so I'll add it to my list of things to add.
