Lanscape Material refuses to compile
Hello again, I come with another landscape problem. I have a landscape material that works all fine and dandy in the editor, but when i try to play from a package version of the game it crashes. The log file says:
I reckon it's something I'm doing with the material thats causing the issue, here is a screenshot of said landscapematerial:

it's messy because I had to arrange it over two monitors to get it all in one shot
Any help or directions would be appreciated, I'm very short on time.
Update: Disabling the normal, makes it compile all fine /
