Ok, before few minutes i finally got free time to load the game, take the screenshot to send with the save file but the situation changed. I wanted to take new screenshot so i can mark exact position and send with my save file but the invisible object is gone. I didnt do anything or if i did i dont know what. The only difference with the game from my initial post and now is that i deleted Spring Cleaning mod and installed Scrap Everything and deleted few objects but not the invisible one. It could be that some object i deleted was affecting this but i'm not sure. Either way that invisible object is gone and i feel stupid. hahaha But i found new one on the right side from the bridge, close to the water and this one can stay. I dont think to build anything there and no settlers walking close to it so honestly i dont care. Still Purr4me thank you for offering your help even if in the end it sorted by itself (or whatever is the reason). I really appreciate your offer, so thank you one more time.
