This mod is the best one that my girlfriend and I have had the pleasure of playing. However, we was only able to give it a 4.5 star rating out of 5 on the Xbox One platform. The reason for this is because the mammoth calf, the guards/the help, and the cow had a glitch to them. I have read your descriptions on Steam and I understand your passion for the art of gaming. Seeing how proud you are of this amazing creation I will address each problem separate so you can find each easier.
THE MAMMOTH CALF: The Mammoth Calf when it traveled along with me it would stomp and glitch my screen so i could not walk anywhere
GUARDS/THE HELP part 1: In the stables, the guards and the stable hands will walk up to random stalls and open them just to take a few steps in then walk out. They do not close the doors behind them, this causes a few of the animals (mainly the Bristle Boar) to leave the stalls and roam the stable.
GUARDS/THE HELP part 2: In the rest of this beautiful Castle, the help (everyone except the ghosts and guards) have a VARY bad tendency of disappearing. We had to quite the game and disable the mod then re enable the mod and start the game up again twice to fix the issue.
THE COW: Riding the cow proves difficult. It is extremely hard to steer (no pun intended) and it is hard to dismount. It would also randomly glitch half way out of its stall door.
Also, a good portion of your teleportation spheres, including the cloud spheres, have fallen from their pedestals. The main ones are the ones Forge and Sanctuary. However we don't know if this is just a temporary glitch or not.
