I tried again and expanded the search for 30 days. 2 games did not load, so I could not examine them. All the others had no Butcher.
Maybe there was a very specific interaction that caused the behaviour. But judging from the fact that there are no current "Butcher gives no coin token" posts, I assume it must be very rare. I don't think there is any more I can do.
In general, copying the game number is important because the game is good enough that any bugs are
a) caused by the interaction of several cards (which may not come up often), or
b) some interface quirk that lead players in the wrong direction, or
c) not bugs at all, e.g. the players overlooked some rule or card interaction (Enchantress comes up often!).
The game number ensures that I and others can see the context as it really happened.
