Festive mash-up missing/transparent textures, when used on a realm!

• This bug only starts when I apply the texture pack/mash-up pack to my realm!  I tested this on my single player world and there was no bug with the textures!

 

• It seems, all non-full blocks become transparent or are missing textures!  Things like doors, flowers, leaves, and torches are all invisible! 

 

• Also, the way to apply texture packs onto a realm are very sketchy, and that could be a part of this problem!

 

The images that I provide will show you the missing textures (With and without the texture pack), and the menu of texture packs that are enabled on my realm.

 

I challenge you guys to release content that isn't plagued with bugs!
