    I'm afraid this very bug bites us quite hard; we have multiple levels situated in the same location, and of course the scenes are copies of each other; and every time a project is built, every single lightmap is recomputed. This costs quite lot of time (5 hours of building instead of a half an hour with Unity4).

    I see there is a note "workaround is possible" - please, can someone describe the workaround? (I sincerely hope the workaround is not "rebuild the second scene from primitives and prefabs", I doubt I would survive telling this to our level designers :-) )
