I have two chests, one outside a factory and one inside. They are linked in input mode, i.e. arrow pointing into factory. The inside chest has a limit of say, 10 slots and it is full.
The problem: The inside chest keeps getting filled with items from the outside chest, which are placed in the orange "limited" area which is supposed to be blocked. I don't know what I can do to prevent this.
Edit with additional info: I'm seeing this behavior with both outside and inside linked chests. And maybe it matters that this only seems to happen with some Krastorio-specific items, at least so far in my save. I've had no problems with any items so far, but the red Automation Tech Cards seem to pay no heed to chest limits and just go fill whatever they want.
