How many slots do the overlay controller chests have (on the right side of the entrance inside)? Do you have a mod installed that makes chests have fewer slots?

I'll post all my mods here in some mints. But I dont think I have some mods wich make my chest bigger or whatever. BUt I have a bunker (or how its name on eng idk... factorio loves to use names with other meaning for naming).

here enjoy all the chaos i exposed :D. Also I would love this mod even more if you could somehow make logistic drones come inside thow...

Yes, that chest in the lower right. It appears once you complete the factory overlay research, and it definitely should have four slots and not just one. Let's see what other mods have affected it. Can you give me a screenshot of the chest's tooltip (what appears on the right side of your screen when you hover your cursor over the chest)? Or just tell me the complete list of mods that appears in bold yellow text inside that tooltip. If the yellow text doesn't appear, you need to enable the "Show mod owners in tooltips" setting.

I have all my mods list on screenshots if you havent noticed. But I am quite sure that I didnt installed any hardcore mods wich make my chest smaller. Also probably its a bug of spawning the chest. I researched the Tech when I was in the building probably its the case of bug.

It doesn't really help to have a big old list of all the mods you're using, I only need to know which mod is affecting the chest. The yellow tooltip says which mod is affecting the chest, so I'd like to know what the yellow tooltip says please.

Okey, its just i exit the game and were razy to come in back for now.

Configurable storage size... When I installed it? Idk...

Yeah, it must be that mod. Configure the inventory size of the container named "factory overlay controller" back to at least 4, and you shouldn't have this error anymore.
