Shader odd with Advent of Ascension

[empirebattles]

I like this shaderpack, but a lot of friends want to use it with a modpack that we have put together, which includes Advent of Ascension.
When we go to other realms, the sky goes white, and all the blocks are black (as if zero light). Torches and light sources dont do anything.

Screenshot example:

(in that shot, the sky should be red, with a red haze, and most of the blocks are red as well)

I know most of the realms change the sky color and some 'tint' in the realm, but i cant seem to get the shaders to work with them :/

The regular worlds are fine, and it looks great!
