Real time shadows iOS on everything but Terrain?

Hello,

I'm trying to get player shadows to work on iOS. In the editor it all looks fine, objects & the player cast shadows. All the static bits are also light mapped. However, in iOS static things form real time shadows on the player, but the player doesn't cast on the terrain -- in fact, nothing casts shadows on the terrain.

I've got the settings to "Fantastic", so everything should be amazing, but still, the player doesn't cast shadows, but receives them. (And yes, "cast shadows" is on -- in the editor the shadows show exactly as I'd expect).

It seems that only the terrain, and only on an iOS device (iphone 5s) doesn't get shadows on it.

ANy ideas?
