Still giving out custom unicorns?
Also, if this mod does not already do so, can you make your horses spawn based on biomedictionary entries? This would allow for better cross-compat with other mods.
I also have a bug to report if WAWLA is installed with this mod. Entities lack localization, it would seem. Also of note is that lances have strange proportions, and I see stuff claiming I can put it in strange spots.
