I would say it is paused (I know a pretty long pause), the main problem is that the RoadWorks mods were not updated which meant staying in version 1.7.10. That itself is not a problem for me, but it limits the abilities to build a city and means everyone that would like to help has to use the same old version.
I have currently installed the correct mods to start the map, which itself was a big hassle, because there is just one single forge version on 1.7.10 where this map with all mods runs stable.
The state of the city is seen in the pictures down below. Especially the coast line is completely bold and unfinished.
And...this project was really important for me and a lot of fun and maybe I will find the time to finish it and will definitely let you guys know here!
