Mixed lighting substractive and shadow mask broken on player only

I have a simple dynamic cube in a scene baked with lightmaps and set to mixed substractive. The cube has a simple material created from Shader forge that supports basic light (no PBR) and lightmap and light probes.

There's one directional light set to mixed of course.

Webgl Breaks, as well on an iphone 6

Editor is fine

If I there's no scene baking (clearing all bake data) then it's fine in the player
