Confirmed, and the cause was worse than a missing quiz. Two quests of Boss Kitty's chain were never generated at all — the one that introduces him and the one that explains the price — so you could reach the Orange Marble quest with no context whatsoever, which is exactly what you described. Both are restored, and the eleven-question quiz now runs; it was never in our files because it lived in server script, not in the client data. The Orange Marble has no other source in the game, so the quiz is the only way to get one. Leaving IN PROGRESS until you have run the quiz end to end and handed the marble in. On the wider point in your report: you are right that this is a pattern, and I have audited it properly — see #251.

Closing this — your v49 run confirmed Boss Kitty's quiz runs and the chain now explains itself. That was the whole of the report: the two missing quests that introduce him and explain the price are restored, and the eleven-question quiz works.

The wider point you raised in the report is tracked separately on 251, which is also closed now.
