where does the horse spawn? from what I've seen its suppose to spawn in the back yard but its not there. is there a way to fix it?

"Horse" spawns near the castle - it will not follow you though - it's being worked on.

cart does not spawn - Horse and Cart are being worked on, and neither have spawn data nor can they be spawned (For instance reseting their data via save fixer comes back with they don't exist)
