Adding any mods that you have downloaded that are extra to the collection here would be really nice as I wont have to manually find the Mods that aren't here, which would be impossible as I see no way of knowing what's missing. You can check all your downloads on Your Profile > Content > Workshop Items > (on the right) Subscribed items > (on the top) > Chose the game Cities: Skylines > and then check the number of mods there are 994 in the collection and I'm guessing there are more than that.

So it turns out there are some missing mods in this pack, such as surface painter, and search box. These missing mods might be due to me not having the DLCs but again they are just assets and the map should load fine. The game loads fine into the Vanilla maps and the Renyolds Harbour works fine, but Greenway doesn't as it gives me the errors I have said before.

Hey! This is so cool! I'm pretty new to the game, but already know some pretty advanced tricks as I've watch people like you and have played similar to this. Whenever I try to install this into my game The loading Screen mods tells me there are 4 duplicates, 271 mission assets, and 81 errors. I have no DLCs except the base game, but I believe that shouldn't be an issue.The loading screen mods gives me this Error:

Simulation: (failed) Object reference not set to an instance of an object.

Once the game finally loads in the map it gives me:

Object reference not set to an instance of an object
[System.NullReferenceException]
Details: No details

I've tried removing all the mods that require DLCs thus far, and it hasn't been fixed. I'm trying a fresh reinstall of my game and mods now, fingers crossed it works!
