highlands does not support many mods (yet?) tho does it it says it does not support forestry bees and wood and does not have mystcraft pages
Edit:
Mystcraft: The symbols for Highlands biomes will be missing.
Forestry: Highlands trees cannot be used with Forestry arboretums and machines. Highlands biomes will work for bee breeding and other biome-dependent aspects of Forestry, although only meadows hives appear to spawn in Highlands biomes.
thats what it says on the forum page[DOUBLEPOST=1373221926][/DOUBLEPOST]
