Pick corruption or crimson; we curate the best world and ship the .wld + map preview.
> Generate worldWorld Rescue (corrupted .wld)
World won't load or got corrupted? Terraria keeps a .wld.bak backup. Point at your Worlds folder - this checks the world and its backup for truncation, shows which is intact and when each was saved, and rebuilds a clean .wld (+ .twld for tModLoader) to restore. Browser-only.
> Rescue world## known issues
- TCP 7777 must be reachable from outside the LAN.
- Changed world paths or ports need matching launch arguments.
- Large worlds can take longer to transfer before first boot.
## compatibility notes
- Vanilla worlds are easiest to host before adding tModLoader.
- Keep the .wld and matching preview together when moving hosts.
