Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Can't Create Tectonic Spray Book

I've been noticing an insane amount of problems in Divinity Enhanced Edition, but the one that's driving me the most crazy right now is my inability to combine a Tectonic Spray scroll with a blank Earth Skillbook to make a Tectonic Spray Skillbook.

What gives :v

I have the same problem. It's clearly a bug of some sort.
