"Best of the Best" Tournament

no, in 3.1, you no longer need to submit the map if it wasn't created using the new generator, as is the case here. The sum doesn't match... it's possible that you have files with different dates in the mods folder (or someone forgot to change another one). Check the identity of the files in the folder. There's no name in the save... Well, it's unlikely, but could someone have confused the names? More likely, the last autosave was made when someone had already exited the game. Try the second-to-last save. If it also doesn't load and mentions the name issue, let someone send it to another person.
