Edited to add: I also got humbled by the Thursday, 12/17 puzzle by Francis Heaney and Patrick Blindauer, which took 8:02. I was so clueless I only noticed the duplicate HORSE while solving.
I finished the very enjoyable Patrick Blindauer holiday Kickstarter set, but made a dumb mistake in the meta. Patrick was nice enough to tell me my final answer was slightly wrong, and I found the error and resubmitted.
