I have a station and use face-to-face connector to connect and disconnect conveyor system between different area. It works for original connect - inset connector pair, but when I use 2 inset connectors, they are always connected, no matter if they are locked or not.
Attached save file is a bug sample. Both group A and B are not locked (light is yellow). There is some ice in container A2 and B2. I can't retrieve ice in A2 from A1 as expected, but for B1, I can get ice from B2 even the connectors between B1 and B2 are not locked.
I have the same bug
