Terraria is a rather popular 2D action-adventure game that’s quite popular in the indie gaming and modding communities. Although there are some differences, the game is quite similar to Minecraft in terms of how the player goes around the world building, crafting and fighting different enemies.
The game is also rather easy to mod and has hundreds if not thousands of mods that add to the already expansive gameplay. In this article, we’re talking about Calamity, a mod for the game that adds many hours of endgame content and dozens of enemies and bosses to the game.
Why does this error happen?
There isn’t a specific reason for this error. There are multiple things that can trigger the issue including
- Faulty update to the mod.
- Corrupt game files.
- Improper installation.
How to fix this?
Here are three fixes you can try out.
Update Calamity Mod and Terraria
The first thing you should do is update both the Calamity Mod and Terraria in case there are any updates available for either or both of them. There’s a good chance that the developers have fixed the issue on their end and have pushed a patch to address the issue among the player base.
Check the integrity of Steam game files
Luckily, Steam has a built-in feature that verifies your game files and reinstalls any files that might be damaged. Follow these steps.
Step 1: Head over to your Steam Library, right-click on Terraria and select Properties.
Step 2: Head over to the Local Files tab.
Step 3: Click on Verify integrity of local files… and let Steam do its thing.
Now run the game again and it should be running all right.
Reinstall Terraria and Calamity Mod
If the aforementioned fixes don’t work, your best bet is to reinstall the game and the mod individually from scratch. Make sure to first uninstall the Calamity Mod, then the game. That way you’ll get a clean uninstall. Once you’re sure all instances and game-related files are deleted, do the same for the mod and then reinstall them both.
