Most of this guide probably still works, but apparently Steam changed the way their Depots work a little bit. For Information on how to fix that, please look in the replies of this post. I haven't tried if any of those work myself, but once I will I might update the guide. Until then, please read through the replies.
What you need
  • Version 3.2.1.7 of Terraria GameLauncher for Terraria 1.2.4.1 from Tool - Game Launcher 3.2.1.5
  • (installed) Steam version of Terraria

How does it work?
The Terraria GameLauncher allows the downgrading to previous versions (including 1.0.0, 1.0.6.1, 1.1.2 and more), however this downgrading feature does not work since Terraria version 1.3, so the goal is to first downgrade Terraria to version 1.2.4.1, the last version GameLauncher's downgrading worked.
When I searched for ways to downgrade my Terraria version, I came across this nice post on the /r/Steam subreddit which explains how you can use the Steam console to download older versions of games.
Sadly, the versions you can get of Terraria with this method only goes back to December 31, 2013, yet 1.2 was released on September 30, 2013. So we cannot get 1.1 or 1.0 versions with this method, yet we can downgrade to 1.2.4.1, the last version GameLauncher's downgrading feature supported.
For Terraria, according to SteamDB, the App ID is 105600, Depot ID for Windows (sadly SteamDB doesn't seem to have any info on Mac and Linux versions) is 105601.
The different Manifests sadly don't state which version it actually is, however it does say a date. Comparing that to the Terraria Gamepedia Desktop Version history, which states that version 1.2.4.1 came out on the May 15, 2014, the closest manifest there is is from June 16, 2014 with the manifest ID 1270558334791485575.
So by downloading the Terraria 1.2.4.1 version with the steam console download_depot command, then installing the GameLauncher into our 1.2.4.1 Terraria version, we can make GameLauncher's downgrading feature work again.
Step by step
  1. BACKUP both your Terraria Installation and your Terraria Saves!
  2. Open the Steam Console
  3. Input this command:
  4. Wait for Steam to finish the download (since it's an old version, the download will be slow, you can see the speed on your downloads page). I would recommend restarting Steam before inputting the command, so you can see how much you've downloaded by looking at the "Total" Network Usage statistic on your downloads page, otherwise the Steam Console will tell you once your download is finished and where you can find it, too. For me it took around 30 minutes.
  5. Locate both your Terraria installation folder (if you don't have one yet, you will most likely have to download the game normally with Steam once since you will want to be able to press Launch inside Steam later on, though it might work without that as well, I haven't tested it) and your Depot download folder (it says where you can find it in the Steam Console after the download is finished).
  6. Clear the Terraria installation folder and copy paste everything from the depot download folder into the installation folder.
  7. Download and Launch the GameLauncher Installer from Tool - Game Launcher 3.2.1.5. It will ask for your Terraria executable, simply direct it to your 1.2.4.1 Terraria.exe you just copied into your Terraria installation folder in step 6. It might also say that it couldn't find a GameLauncher folder in your Saves folder, you can simply ignore that and go on with the installation.
  8. Start Terraria via Steam, it should open the GameLauncher. In there, you can use the "Downgrade Patches" option at the top to download whatever patch you want. It will then show up in the list and you can simply Launch the Game in the downgraded version.

GameLauncher creates a new Saves folder for each version, so your Characters and Worlds shouldn't interfere with any of the versions. However, it's always recommended to make a backup because it might still get corrupted in some weird ways.
