Prompted to reinstall Terraria after opening it, and character missing after reinstallation
I opened up Steam and went to Terraria, but instead of saying "play," like it usually does, it said "install." So I installed the game, even though I had never uninstalled it in the first place. After the install, everything was exactly the same except one of my characters was replaced with a blank character slot with 0:00 play time.
All my worlds were still there, as well as the one other player I had.
I also found a world called Unknown World and loading it causes the game to crash. It's actually the size that's unknown it has no name.
How can I get my character back?
Well as I can't comment... I will try to help you as much as I can from what you have written. It seems you are not the only one having this issue. On the official Terraria forums there was a discussion about it and how to possibly get your character/world back. Here is a thread that was discussing this.
To make it easier so you don't want to read it all.
- There was a suggestion to look into your file with saved characters (if you had not saved them on cloud) and you should see 2 files with your characters name, one PLR and one PLR.BAK. Delete the PLR file and rename the PLR.BAK to PLR and you may see your character again.
- If you don't have your character name in here check the Recycle bin if it did not delete itself (there was a bug causing save files to delete themselves)
- If you get your files back from the recycle bin and still can't access them you can try to edit them in the Terraria editor.
