Was just in the savegame when i loaded it with 1 notch down, i put the notch back up and loaded an earlier savegame, map is ok now.
And i only explored the first map.
Not really NEED a solution now, but thanks for the fast reply and clearing this up for me how this is possible is always welcome.
It must of has something to do with altering the sound speed..

There are wounds that bleed inside us There are wounds we never see They are part of our refinements That allow a man to be There are wounds that bleed in silence With aristocratic grace There are tears we keep beside them Never seen upon a face
