Yes!
It's in the latest patch notes
To reiterate:
Mods can safely load both GM and Story data without causing issues such as disabled characters in a new Story game. All story goals are now parented under a respective Story/GM/Arena goal (DOS2ModWrapper/GMModWrapper/ArenaModWrapper). Existing mods will still work, but to make your mod compatible between game modes, make sure to parent any modded goals under the newly added root goals (DOS2ModWrapper/GMModWrapper/ArenaModWrapper).
