Yeah i know all that **** ok ? This is not bug, i messed up something on interface folder and i didnt know which image and i dont want to download PWO client again just to fix this. I been here longer than you so yeah whatever this cactus thingy. Go plant some cactus or something.
Did you check your sprite folder to make sure that the sprite you were using is there? The default one would be in the folder named "1", or if you were using the lance one, it'd be in "3"
Im using Lance sprite and yes all my sprite folder is okay, this happened after i edit some moves image provided by Reiatsu here http://forum.pokemon-world-online.net/showthread.php?tid=33068.
