This is more or less echoing an old bug report I made in September, with some elements of the more recent updates.
Basically, the game allows me to build an automation bridge over an AND-gate if I build the AND-gate first and the bridge second. If the bridge is placed first, the gate can't be built. I understand that this was a valid and working configuration before (I've used it), but now I am able to build it despite it being an invalid configuration as indicated by the "Building has overlapping ports" error.
Further, the error message description which I can read by clicking on the AND-gate is somewhat misleading, at least in the first part: "Invalid Port Overlap: Ports on this building overlap those on another building. This building must be rebuilt in a valid location." But, each of the 5 ports here is in a separate tile, so I do not understand why the ports are considered to be overlapping.
And I'll echo my plea from the last bug report: please allow us to use this build, it helps keep things neat and small, why forbit it?
Steps to Reproduce
Build AND-gate (or OR-gate). Build automation bridge. Get "overlapping ports" error for building an invalid configuration. Also unconsisten, as building the automation bridge first and the gate second is not an allowed build.
