My horse doesn't want to jump anymore

[simsonata]

My sim has been taking her adult horse to the training grounds for ages and training him on the jump course. Now, he's suddenly refusing to do the jumps individually or the full course action despite having no problem up to now. He just shakes his head when I try. His needs are static so he's not tired or anything and he doesn't have negative moodlets so what's wrong?

Do you have any cc (custom content) installed?

[simsonata]

No I don't.

Could be routing issue, can try putting a jump course in your lot and see if the horse jumps?  Also might help if you turn off needs static, let your horse fatigue moodlet wears off, then have horse try jumping again.

I never thought static could be such a hindrance! I'll try that, thank you.
