Lightmaps are not set as "Read only".
This issue is not caused by objects as I experimented and compiled lightmaps on empty terrain but it still persisted. To my knowledge, it is caused by terrain. But I have no clue why.
Bugged lightmaps look normal in editor.
Edit: this issue is NOT RELATED TO LIGHTMAPS. Even if I remove lightmap folder entirely, the issue still persists.
I'd be very happy if someone could help me or suggest something. Thank you in advance.
