No... we do not mean if you find any bug Pokemon to report them... we mean problems with the game. If you see any glitches or anybody using exploits, please report it. By reporting such bugs and errors, you will be helping Pokemon Opal to become bug free!
Please remember to include every detail when you report something. Also be sure to include the time and location that this occurred.
"Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." - Brian Kernighan
