I'm having a problem a couple of my multiplayer games. I can't build any harbor buildings in my ports, such as fisheries or sub bases, on a couple of my islands, though others are fine. Whenever I try placing a building, it just says port area blocked, even though it clearly isn't. My friend isn't having any issues like this. We've tried restarting and reloading the game to no avail.
Anyone else have this problem or know a workaround?
This is a known issue for me. This happens when you somehow block a lets call it :"critical location" (program fucks up itself) so this bug happens. This can also escalate by you not being able to build ANY port authorities either. Happened to me a few times that I blocked my Harbor area and that made it not only to block further buildings in that area BUT not being able to construct ANY new port authorities ANYWHERE on my island too. This can be a nasty bug.
Can fix it by removing the last placed building then placing it somewhere else so you avoid that "critical location"
I don't understand the rules for building in a harbor - or perhaps it's bugged. It's much easier for example to build a fishery so that it's adjacent to and aligns with another fishery. If I move it one space away it won't let me build it. What I do now to help prevent blocking is to build a pier that juts out from the Warehouse and I then build a bunch of fisheries on both sides of the pier adjacent to each other. I don't build fisheries along the coast anymore.
The fisheries need a certain amount of free tiles in front of them, if you move the fishery to the front, then this area may interfere with the area that should be unoccupied from the adjacent fishery.
I run into this differently where randomly one section of the building area will be red even if nothing is on the shore to be blocked. It's usually a square shape chunked out of the semicircle that the harbor building creates. It's almost as though the game has a different layer to prevent buildings that conflicts with the harbor building area.
