If you are still having issues

Load Steam From the Library section, right-click on the game and select Properties from the menu. Select the Local files tab and click the Verify integrity of game cache... button. Steam will verify the game's files - this process may take several minutes. Once the process is completed, the Check Window will automatically exit.

A new patch and expansion was released not long ago, and you may experience issues like missing textures/objects/assets, game crashes, weird/non-functional user interface.There are a couple of things you can do:---Since this is a large patch, and with it the release of a new expansion, it is likely that a lot of mods are conflicting with your updated game as some of these modifications may not be updated yet.Instead of unsubscribing from your mods, you can also temporarily deactivate all mods by adding a launch option through Steam:---Existing savegames may show problems like missing textures and assets, especially if you created this savegame with mods enabled. If the mods are disabled, they cannot be loaded and might result in weird looking maps/cities. Best thing to do is creating a new savegame, or use a savegame that is not showing these issues until the mods you're using have been updated.---Make sure your game is not corrupted, or is missing any files. You can do this without reinstalling the game by verifying the integrity of the gamecache.
