I have a region with three cities in it, all about 100 - 150k in population. Got the university in my education city and researched the Solar Farm, then started building it. Two of the three cities see that it's being built. The third got the "Solar Farm unlocked" message, but shows an empty great works site. I can't send any resources from that city. Tried letting it run while I read for almost an hour. Still shows an empty GW site - no Solar Farm being built.
Anyone know a fix or workaround?
I've tried this several times and have realized that if you click "BUILD IT" on more than one city then there's a bug and the Great Work synchronization will freeze for those cities you clicked to build on. What I do is I build the Great Work using only ONE city, I know its taxing but what to do, I use sandbox so its possible for me to import all the resources, although you must have a huge city anyways in order to supply the workers.
After the Great Work is built, THEN I go claim other cities, and just WAIT. I click on the Great Works icon and wait, soon it will show up Arcology Unlocked, or Solar Array Unlocked, (depending on which one you built), the button will show up for you to click and Build It, but DON'T, DON'T, DON'T click it! It will take you to the "Getting Permits" dialog box forever. What I do is I just WAIT. Then a minute later it seems the Great Work AUTOMATICALLY builds itself. It shows you Phase 1, resources will automatically be shown as being sent, then it will go to Phase 2, resources will be shown as being sent (which were actually being sent by your first city). Eventually you'll see the Great Work built and you can make use of it.
Here, here are the pictures.
STEP 1 - CLAIM ONE CITY AND GROW IT TO BE HUGE AND FULL OF PEOPLE (THIS IS KAZOO PASS, BTW)
STEP 2 - USE THAT CITY AND BUILD THE GREAT WORK ALONE, DON'T USE OTHER CITIES!!!
STEP 3 - NOW THAT YOUR GREAT WORK IS COMPLETED CONTINUE SENDING IT RESOURCES ETC.
STEP 4 - CLAIM ANOTHER CITY, NO NEED TO BUILD ANYTHING, JUST CLICK GREAT WORKS ICON AND WAIT, AFTER FEW MINUTES THE BOX TO BUILD THE AVAILABLE GREAT WORK WILL SHOW UP, DON'T CLICK IT!! JUST WAIT AND THE BOX WILL AUTOMATICALLY CHANGE AND THE GREAT WORK WILL START BUILDING ITSELF. AS ITS ALREADY BUILT BY THE ORIGINAL CITY IT WILL SIMPLY SIMULATE THAT PROCESS HERE.
STEP 5 - WAIT. YOU WILL SEE THE GREAT WORKS SITE BEING BUILT IN THE BACKGROUND FROM YOUR CITY. EVEN THOUGH ITS ALREADY BUILT BY THE ORIGINAL CITY, IT IS SIMPLY BEING SIMULATED HERE IN YOUR CITY, IT WILL BE COMPLETED AT THE RATE AT WHICH IT WAS ORIGINALLY COMPLETED.
STEP 6 - DONE!!! GREAT WORK WILL BE UP AND SYNCED AND READY TO USE IN YOUR CITY. CLAIM ANOTHER CITY AND DO THE SAME! HERE THIS NOW GREAT WORK IN ANOTHER (THIRD) CITY. (THIS IS SPOONER PLAINS BTW).
This way you can get the Great Work for all your cities in that QUADRANT. Note, if you happen to click BUILD IT on another city while the build process had already been initiated by someone else, it will show you this bugged, forever loading screen.
ERROR / GREAT WORK LOST FOREVER IN THIS CITY.
There's no way around this. Great Work will be LOST forever on that particular city. No way else but to start new region. So remember, DON'T CLICK "BUILD IT" on multiple cities, just build it using one city, and then even when the button shows up to Build It, DON'T click it, just wait - be patient and the screen will automatically update itself. As you can see above, empty other cities, but Great Work site automatically built.
Hope this helps.
