I too am getting road issues with the Akar mod. I loaded an already built city in order to add parklets and some plopped industrial to find that I could not plop anything. Could not intersect with existing roads and bulldose tool only worked with buildings. The RCI plopper allowed me to select building and gave me snap points but when clicked, no plop. It would just bulldose the building that was there from zoning. Shut game down reloaded to new region and then I could plop, but only low density, low wealth. Closed it again and reopened same region to find that again could not delete roads, zone roads, or intersect roads with new ones. Must be an issue with the configuration of the Akar mod packs, but I need help. I had read the bridge and tunnel mods causes issues, so i deleted that prior to installing akar mod. i also deleted UDoN mod that i already had prior to Akar Roads pack. Any insight/help would be greatly appreciated.
