Lighting doesn't bake 4.12 project

Greetings all!

So I’m working on a prototype level that’s using water that’s only compatible with 4.12. I have migrated the desert race level from vehicle game for some of it’s assets but when I attempt to build lighting it loads for one second and nothing happens. After running into this problem 4.12 I figured I’d try to load it up in 4.14 and just kill the water but now it’s not even letting me create a 4.14 version of it. There’s something wrong in there but I am not a good enough trouble shooter to figure out what it is. Any help would be greatly appreciated

Are you sure ‘‘force no precomputed lighting’’ isn’t ticked on? Could be that.
