There was that attempt by me to go more than 8km away (until you swiftly applied the admin authority bat, or rather it was yqt that applied it), but I don't know if that was cropped already. Fiah may have done a bit of explorinig, but other than that, I don't think there has been.
There may have to be some cropping of already explored but unused lands to get horses to spawn though.
i swear to god if we crop for 1.6 i am going to flip my shit
Why? We might have to crop somewhat in order to get horses to spawn.
