Talk: Bugtracker Guidelines

I have had a glitch where the horses in the mod change into the Donkey Model instead and I don't know what happen, it was fine for a couple years and now I can't change them back to the normal Horse Model. I haven't messed with the code in the mod it's self at all, I only used the available settings I am allowed to config on Minecraft. I am using other mods so I may be the cause but I just want to make sure I'm not the only one who has had this problem before. Any thoughts of how I am able to fix this bug?
