2 place looks incorrect. i already tried to change names in userstats.dat file with text editor (Kate) but after that all places looks incorrect (like ?). How i can fix that?

@ MaksDragon: This bug is known (at least to me), and I probably reported it in the CS2D Bug Reports.

It's caused by a typo of the developers when checking to ensure that a name does exist.
I assume that they check if the name length is greater than one instead of greate equal than one, so names with only one character are dismissed.

@ Mami Tomoe: I think that's a little bit more complicated than that. I've seen this happening, it's related to the way requests for result is handled. I might take a look at it some time, but this doesn't seem like a problem.

@ SQ: I've already investigated this myself, what you're referring to is less common and less of a problem.
I recall looking at the stats file and seeing that those players have a 1 character long name.
