psatkha, am I understanding you correctly, should I receive all the "fast" creatures? And regarding the file name, yes, that's correct... it's just an unnecessary operation that can be avoided.
I don't consider a speed higher than 9 to be anything unusual... 1) there are arenas larger than the basic ones, 2) high speed is used so that a creature can reach from one corner of the arena to the diagonally opposite corner... but you know better.
Regarding speed higher than 9, ask the respected comrade Nargott! I honestly don't remember any standard creature with a speed higher than 9 units!
Yes, send them to my email, or post them here!
