So this basically started when i copied my project over to a hard disk, because I was resetting my PC. Suddenly this message "Failed to load tileset data" started coming up and I can not open my project or game. I've looked for solutions to this problem such as replacing the tileset data with a clean one. To no avail. It doesn't look like any of my tileset files are damaged, so I don't know what the problem is. Could anyone help?
