Still amazed at how cheap WBs are. I'm used to 20k+ mares and not a lot of them, it's like Christmas on WBs side, 10k per mare. Here went my profit haha
I wouldn't fire your riders again, that gets expensive to replace them. You could just change their training on the rider page so they are all training in Eventing again so they'll gain points in all the disciplines in future trainings.
