Hi, thanks for your help (you too Sheson). I'm sorry to still coming, maybe i'm super dumb but the problem persist. I did what you told me, to know checking the window behind. It had a warning with snow in snowy ships- seasonal but i removed the mod for LOD generation. The problem still persist i got an error with circular seasonal swaps in Unfrozen_SUM.ini. Which i don't understand because i removed all lines with LOD or DynDOLOD in the file. I'm a bit lost i admit.
Sorry to bother.
