Lighting needs to be rebuilt

Hi
I’ve built a fairly simple puzzle game which procedurally generates a puzzle each time. Whenever I run it I get a message saying lighting needs rebuilding. I figure this is because the meshes are random, so different every time, but what is the best way to handle this? Obviously just rebuilding won’t work.

I’m using a default lighting set up from the blank template: directional light, skylight, sky sphere.
Thanks

In world setting there is a boolean called force no precomputed lightning (or something like that). After you click it you would have to build light once more and it will be everything (or at least it should)

You can just use movable lights and you’ll never have to build lights again.
