Apparently, this problem was resolved several times in the past, however it’s still happening. 

The game was crashing for me numerous times in the past and I didn’t understand why. The issue was supposed to be “resolved” as my last issue I created said it was. But I now know the main cause of this issues: it’s the custom skin. 

To prove my point, I switched to a pre-made Minecraft skin and the game did not crash a single time within days of playing. The second I switched back to the custom made skin, the game froze and crash and I lost my horse upon reloading. To further prove this, I decided to take a pre-made skin and put the Founders Cape on him.....and the game froze and crashed within an hour of game play.

I really love this feature, but this feature really hates the game.
