I assume you put in a condition that prevents the animation from being used, right? I use IsRidingHorse == 1
Nope, but even if that might work this doesn't explain how they did it correctly within other mods (and without odd conditions), like Chryslus Club, UMPA or so. Chryslus Club puts some animations as "Loose" just in the section and they seem not to interfere, however my (or copied) do weird stuff.
Thanks anyway.
