Carloquiga Ok, try these suggestions and let us know. After making a change to a map/level always save it right away.
When making changes to something like the "lighting" two methods work on updating when doing another test run.
First way is to place a new "light marker" and saving right away, then test run again and see if it changed... if not..
Second method, works best, make changes to your light markers, save it again, open up your "Levelbank/testlevel folder.
Inside your "testlevel" folder delete everything inside it ( don't delete the testlevel folder itself, just everything inside it )
These files are the lightmap files from the "Last" test run. When you do another test run NEW lightmaps are built
and your changes will now show

See it's not so much a "bug" your test run is using the "last built" lightmaps over again
until you start a new map.
Also .... you made a LOT of changes there I see. What do you mean by

Did you like "remove" the sunlight settings from the setup.ini ???

Or anything else from the setup.ini ?
Also don't confuse "ambient lighting" for any of this.
My games never have bugs. They just develop random features..
Lots and lots of random features...
