Frequently Asked Question:

Do I need to download all the asset dependencies?

Nope! The only *true* dependency is the Network Extensions mod. Of course, if you load the map without the custom map theme it will not have the same desert textures, so we highly recommend you also install the custom map theme. If you’d prefer to not bother with the custom foliage, feel free to load the map without them and add your own!

-----------------------------------

I loaded the map and the textures are not showing up, what do I do?

First, make sure you’re subscribed to the “Arrowhead Valley” map theme. Next, ensure when you load your map you’re selecting the “Arrowhead Valley” map theme in the dropdown menu. Finally, it appears there’s a bug with map themes right now where simply clicking “continue game” will load the map without the custom map theme. Using “load game” is the most reliable way to avoid having issues.
If for some reason you still can’t get your map theme to load (or any map theme on any map, for that matter. This seems to be a global issue) you can try using the “environment changer” mod to “refresh” the save by first loading the game with the “none” map theme enabled, saving, closing the game, then loading the save with the correct map theme again. I can’t 100% confirm or give detailed instructions on what combination of saves/loads will properly refresh the savegame, but I’ve been told by others that this method is effective

I get a “System.NullReferenceException” error, how do I fix it?

“System.NullReferenceException” occurs when an object is “called” in-game, but the asset the game is calling isn’t found. This can happen for a number of reasons, so it isn’t always easy to diagnose.
If this happens while loading the map: make sure you have the Network Extensions mod not only installed, but enabled in the mods menu
If this happens while playing the game: ensure you haven’t accidentally disabled all the possible vehicles in a given category in the Advanced Vehicle Editor. If this is the case, once the game tries to spawn on of these vehicles, you will get the error.
Beyond that, the best thing to do is try removing all the mods you don’t need to run the map. 99% of the time, it’s either a mod incompatibility, a missing mod that you may have previously had enabled, or a setting in a current mod causing the problem. Troubleshooting game crashes comes with the territory when using lots of mods, unfortunately.

-----------------------------------

My game crashes when loading the map, why?

Sometimes when loading a map with lots of assets in Cities: Skylines the loading screen will “hang” for long periods of time (even upwards of 15 minutes, depending on how many mods you have and how fast your storage device is). This is completely normal, and sometimes your OS will tell you “Cities: Skylines.exe has crashed!”. If this happens, and you are given the option to “wait for the program to respond”, click that option and continue to wait. Sometimes, however, your game will simply crash. If you can’t seem to get the map to load with a large number of assets, try the “Don’tCrash” mod. This mod is often times critical for loading savegames with a large number of assets (and is included in our Arrowhead Junction mod collection!).

Keep in mind that the only true dependencies for this map are Network Extensions and the map theme, so you don’t need to subscribe to our collection (or the foliage listed in dependencies) in order to run the map!
