I can't talk in any world even in servers and i can't see them but commands still work but i can't see them. it started when i uploaded a new skin from http://minecraft.decx.org/ Beasley skin armory getting my new girl skin. then when i was done downloading the skin to mincraft i started to go on minecraft server's. first it was relay weird blurry stuff but i fixed that my self and chat is on fore every server and world
