Did you give them any weight in any of your towns and econ regions?
I've never seen a Geocore. Should they even show up on a non-Metra map? You should go into the allowed industries list in the editor and just turn them off. Then start a new game on the map.
A new 10 year scenario starting in 1910 with 3 competitors. All existing track removed. Unfortunately this file is a bit too large for upload to the Terminal. I can email you the map if you want it.
I don't see them disabled in any of my regional or city settings, and they're not disabled in the "INDUSTRY WEIGHTINGS" under the MAP OPTIONS either. Is there another place to look?
Also, where would I look to see why the GeoCore is showing up immediately in 1830 instead of later in the life of the map?
Ok, same map - now that I've started playing it...I have the map start in 1830. Yet immediately, the map has GeoCore map items on it, and they're as common as anything else is. But shouldn't there be some sort of a "start using this item" date associated with it, since it seems like it would be a pretty late-stage item in the game. By the same token, I have been playing for a while on this map, and ZERO steel mills, dairy production (I have milk production), or canneries have appeared. Meanwhile, my factories are no longer accepting iron (presumably because it would be going to the steel mills), so I have nothing at all to do with my iron sites.
I'm confused as to why this has happened, because they're not disabled anywhere in any of my settings (regional or city).
