It's not a serious Bug. Also I have a special unique Texture for failed Textures, so if you click it then its your fault
I fix it when Minecraft itself decides to make an easy Client->Server Update, like worldObj.addBlockEvent currently does Server->Client.
Progress on the 1.5-Update, 62 Textures splitted, over 9000 to go...
What was that? How many to go? XD
