First :

I have recently found out that sometimes chimera horses have bugged hair, when mane is changed. Part of the natural mane stays on, while it should remove all natural mane texture.

Here are my examples

No. 1:

No. 2:

Second:

When equipping tack on a horse, the mane shouldn't be under the saddle, saddle pad or the blankets.

It would make more sense if the mane would go above the bridle, saddle, saddle pad, blankets etc.

It would add more style, and better looks to the game.

Examples:

No.1:

No.2:

I dont know if the second bug is really a bug but I report IT just in case.
