Was doing a little bit of the new crime, ran into a silly but harmless glitch. Senior Female target with a Family scam. I got into the Low Reward zone via a Curious, then used a Regretful message to dip back down into the High Reward zone. Instead of the usual "Your curious/reminiscent message" text, the word "regretful" was replaced with the target's email address. Beyond this it all works afaict but this does look pretty funny.
I have not seen this bug with the other options, nor on other types of scams. At least not yet.
