Crashes and teaching about nearley-playground HOT 4 CLOSED

I made an example to show the students how this could work, but for some reason the nearley playground interface doesn't loop through all the options. It's stuck on "linguist" for PROFESSION. The linguist has now been shot, hanged and drowned for all kinds of silly reasons. I'm dreading what will come next.

Any idea why this might be?

MIDSOMER_MURDERS_PLOT -> LOCAL PROFESSION FOUND DEAD PLACE SUSPICION SUSPECT ANGRY BLAMED THREAT THREATENED
LOCAL -> "A local "
PROFESSION -> "linguist" | "philosopher" | "novelist"
FOUND -> " is found "
DEAD -> "drowned" | "strangled" | "dead" | "tortured to death" | "hanged" | "battered" | "suffocated" | "shot" | "knifed" | "nuked"
PLACE -> " in the coffee shop." |" in the swimming pool." | " after band practice."| " behind the primary school."
SUSPICION -> " Suspicion falls on the village "
SUSPECT -> "baker" | "pastor" | "mailman" | "florist" | "nerd" | "twins"
ANGRY -> ", angry that the "
BLAMED -> "new wind farm" | "pig" | "pub" | "decline in newspaper reading" | "metric system"
THREAT -> " might threaten "
THREATENED -> "the village fabric." | "what little sexual tension the village has left." | "the Old Inn." | "the cow farm."

Hi is there anyone who can help me please?

Alright... well. Tired of waiting. I wrote up a tutorial anyway. Happy to hear back about crashing and freezing.

I added infinite loop detection, so the crashing should be much improved.
