Sorry I should have been more clear, it does work for local servers which is why I am reporting this in the realms section. There is a slider which allows you to change the texture pack from 16X (Actions and Stuff Texture Pack), 32X (Vanilla + Visuals of Actions & Stuff), and 64X (Vanilla Only with Animations). I try to change the slider in my Realms world and it won’t change, only having the 16X texture pack on no matter which setting it’s on. Apparently it has been a known issue for a while now.
Also, I have heard this happens with many other addons with their own textures.
