Horses, donkeys and mules with buggy texture

See MC-122005, caused by outdated texture pack.

Are you using the "Programmer Art" resource pack?

I'm using the default textures.

Can you please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder]) here?

I just checked if I had other textures and yes, I had the V2 version of the Jappa textures. I'm so sorry, I hadn't noticed. Next time I'll check that, thank you for the assistance.
 

No worries!

Thanks 🙂
