In that case I need to ask you to find a descriptions file that isn't a liar and upload it for all of us, because for the longest time, Marbles Moonsault DDT has read as high damage, medium cost :S and I'm wary of whatever else might be wrong in the descrips file I have.
Alternatively, maybe it is just a legit descriptions error, but for me at least it's always read that. If anyone else has Marbles Moonsault DDT reading as high/high then something's wrong with the copy I have (I just updated last night too - booted new client, got newdescrioptions.ini and changed it to replace my current descriptions.ini), which also means it's probably wrong for a lot of people.
This seems like a tedious task but you don't happen to have a file yourself that states what move descriptions SHOULD be compared to what they wind up reading in the current commercial descrips file that goes around, do you? I'd be more than happy to take a look at that and mark what moves don't read as they should, or something to that effect
Severely doubting you have something like that though.
