Sick and tired of UE4 having its own mind - suddenly broken lightmaps

Did that too - switched to Force No Precomputed Lighting, saved, closed Editor, re-opened, reloaded project and made sure ligthmaps were purged (not present in World settings tab under Lightmass). Switched off Force No Precomputed Lighting and re-built lighting in Production quality. Still got the same exact look as in the screenshot in OP.

IIRC You need to hit ‘Build’ after hitting Force No Precomputed Lighting. Lightmaps aren’t purged until you try to run lightmass again.
