Looks like possibly an issue with older YA/GU2. Are you on the latest version of both?

Thank you, now it is OK.

I find this problem again now. Report:
Exception drawing Frilleus341620: System.TypeLoadException: Could not resolve type with token 0100006a (from typeref, class/assembly GiddyUp.Jobs.JobDriver_Mounted, GiddyUpCore, Version=2.0.66.0, Culture=neutral, PublicKeyToken=null)

Still by disabling the animal walking animation can fix this bug.

May need the HugsLib log to be able to try and fix it.

From the log it seems you're using the original Giddy-Up with the addons, not Giddy-Up 2 (it has the addons included). It has a different workshop page:

Many thanks.

First time this appeared here:

Could not find class yayoAni.YayoAniSettings while resolving node ModSettings. Trying to use YayoAnimation.YayoAniSettings instead. Full node: <ModSettings Class="yayoAni.YayoAniSettings"><OnlyPlayer>True</OnlyPlayer></ModSettings>

Since 1.6 there seems to be an issue again with GU2 Forked:
