Inconsistent behaviour observed:
During the other days's challenge, there was a bounty for a left-facing cyclops. I clicked a right-facing cyclops and it did not count.
However for rats and gargoyles the orientation does not matter.
Ah, good point! I wonder if I should make congruences for L/R - they are technically different monster IDs, but I think they should count. Thanks for the report, I'll look into it!
