I’m having the weird issue where, whenever I add one mesh to the level from now on (doesn’t matter what mesh, I tried multiple),
my next lightbake is suddenly much darker then before (without changing anything light-related, only adding the one mesh).
After I delete the mesh again, and rebake, the lighting looks normal again… Pictures for illustration:

I had this in 4.11 already and upgraded to 4.12 today, but the problem persists.
Tried lowering some lightmap resolutions. Tried adding just more than one mesh.
Copied all the objects to another empty level. Same issue.
Anyone an idea, this has been bugging me for days…
