A few questions. Were you inside 202 when this happened? Was Shy the ghost during the run? How many lamp charges are left?
Edit:
This one is little absurd because it seems light intensity has reach over 100 or something. There's nothing in codes that would cause such results. I was gonna upload a little fixed version but I will wait until I can replicate this issue.
