If any lads are curious, here's the finalize spawn zone for Bouffalant. I worked with some ledditors/discordtrannies to collect as much information as possible to sort this out. One of the ledditors wrote up a post to explain how we determined these lines. Kinda funny how it doesn't reach Buffalo NY.
