Sounds like a bug

@Rylee. It may not necessarily be a bug. Next time, try working with OP and asking them questions to try getting down to the main point of WHY they are struggling before simply saying it's a bug because at times, there are steps that prevents a player from sending horses off to being worked as a Career horse.

@Skye, if you are not having any horses showing up underneath the Estate -→ Career button, there could be a few issues.

Firstly, is your horses' path set to Career? Preferably some users set horses to doing Careers and Careers only, so their working path, underneath the Edit button and ticking the box and making sure the dropdown menu has Model selected in the proper area. Make sure the other boxes are ticked off ((This is ONLY if you want your horse(s) in question to be Career horses only.))

Secondly, if they are an adult horse, either wild caught, bred or bought from someone else, it is possible that their Personality hasn't been fully unlocked and to do that, you go to the Vet place and one option there will have a Personality test, you can select the horse(s) from drop down menu and go through them all. Due note, last that I recalled, that the final horse just has the “page” loading and you have to move away from it for it to register the horse being cleared.

If these two don't work, let me know.

@TheDustyAngle thank you so much, i did manage to figure out some of the model hoses but i will look into the personality at the vet.

No problem. Whenever you get new horses, no matter if bought, bred or captured in Exploration, always make sure the Working Path is ticked to what you want it as and their Personalities are tested.

That helped the problem, thanks again,
