This may just horrific luck, but it seemed too coincidental not to post.
After the update (which removed palibashing by hand), I used a wrecking ball to destroy two palisade walls on my own claim. Everything worked normally, but there was no splash damage on either section when it was removed (that is, only the segments hit by the ball were destroyed). It was the first time I've ever had that happen, and thought it might have been an unintended consequence of the change. If my luck is really that bad, well, I guess I should find some pearls washed up on a beach tomorrow.
