I know this has been addressed but there's a lot of the same advise out there. This is more for after you have tried some troubleshooting. The problem I'm having is after attempting to build a Great Works project (in my case the Arcology), I am unable to send and resources to it. My city specializes in alloy and metal production. Here is how I have it set up:
Global Market for Alloy: Set to "Use Locally"
Traffic: Moderate but not an issue
"On" button in Arcology Regional screen (used to start sending resources): Green on all resources
Trade Ports: Full of Alloy and maximum amount of delivery truck garages
When I look to see if trucks are even going to the Arcology in the regional screen, they are not. I successfully sent 20 alloy, then it just stopped sending. I have restarted the game, still nothing. Does anyone have any advise on how to fix this issue? Maybe there's a patch I haven't heard about? Love the game but DAMN is it glitchy.....
