Clean Uninstall/Reinstall

*Make sure you backup your saves folder before moving on any further*
Save game location C:\Users\<WindowsUserName>\AppData\Local\Colossal Order\Cities_Skylines\Saves
*Make sure you backup your workshop or at least the folder 255710 before moving on any further*
Location: C:\Program Files (x86)\Steam\steamapps\workshop\content
*Make sure you backup your appdata/Colossal Order folder before moving on any further*
Location: C:\Users\Game2\AppData\Local

*If you have assets missing after resubbing as above then copy the missing items by writing down their workshop numbers, then search your 255710 folder and copy them over to your new workshop folder.
