Factorio: 1.1.35
Lightorio: 1.1.2

Hi,

Thanks for the report and screenshot. In a vanilla + Lightorio only game I'm not experiencing this issue so suspect it's a mod conflict. Can you upload a copy of this save file and I can take a look.
Thanks
Jack

I don't have a one right now, but it happened with this modpack: https://mods.factorio.com/mod/zo-pack/downloads

Hi ZwerOxotonik,

As discussed over discord, the issue is with water placable lamps:
https://mods.factorio.com/mod/rz-water-placeable-lamps

this mod overwrites all lamps in the game to be in a different collision layer, including the lamps Lightorio adds. Lightorio's lamps aren't meant to be collidable objects. I'll send a message to that mod author.

Thanks
Jack
