Importing Scene and Lightmap to another project

Hello,

We are working as a team here, and from time to time we have to merge the projects. I've been doing the lightmaps on my computer, and now I imported my coworker project as a whole, made a Unity Package by exporting the assets I had editted, including the SCENE AND LIGHTMAPS, both, and importing in the new project. Basically everything worked, except for the lightmaps... they are still linked to their respective scenes... but wayyyyy too bright, a lot different then what they were before... and I am on the same machine that made the lightmaps in the first place, just a different project...

Both project settings are exactly the same, bot are targeting iOS, both are exactly the same, but in one of the projects the lightmaps show correctly, in the other they dont.

How can I send a Scene AND Lightmap to another project without screwing the lightmaps up? Apparently "Export Assets..." does not work properly in this regard -.-

Thanks in advance!
