How do I get to the update my freind said download the source code but when I did it put the source code in a word doc so what do I do?!
If your game is version 0.8.0 or later then there should be an auto-updater feature already in place. Basically when you open your game there should be a prompt saying "There is a new update available! Do you want to update your game?" Just say yes and your game will automatically update.
If your game's version is earlier than version 0.8.0, then there is no auto-update feature. You will have to go into your settings, click the "Open Data Directory" button in the bottom left corner, go into the "saves" folder, and copy the folder(s)/file(s) that are related to your clan. Then, download the new game files, open the "saves" file just like the other game, and paste the files you copied. You should be all good after that. If not then I might've gotten something wrong since I've never transferred my clans over before. If I am wrong then check in with the discord or look through the replies of comments above. Hope this helps :)
P.S - Updating your game has nothing to do with replacing the source code :P
