The Chroma Hills texture pack causes a lot of loading issues and crashes.

First, loading my world (on a realm) takes longer than normal whilst loading the texture pack.  Both myself and other players notice suspiciously longer loading performance issues with Chroma Hills. 

Then, there are crashes that are occurring since we began using Chroma Hills:

• accessing the xbox dashboard will cause the game to crash and sometimes force restart of the console.
• randomly at times it will disconnect me from realms, and when it loads the Minecraft main screen, the background is solid black with the text in the font of Chroma Hills.  This sometimes forces a restart of the console to join again.
• If I go to: Realm settings - Download world, it fails 100% of the time.  I tried on both on my Xbox and Windows 10 edition and it is impossible to 'Download World' (of my realm) with this texture pack enabled.

All-around the loading and crashes combined seems like there are some bugs with this texture pack.
