Yeah, it's the second time this happens to me, and this time I'll make sure to have a backup. Well, this time it didn't exactly erase, but Reimu-A's Extra scoreboard got corrupted and crashes my game, and that also might explain why often my game crashes when I attempt to save a replay.
Anyway, could someone, preferably who has 1cc'd Lunatic with every shot type, upload their scoreth11.dat? I do have Jaimers' "pack" of score.dats here, but TH11 is missing from there.
