yeh.... recently i've gotten this weird ass thing with uke and tori.
Uke looks different and got a radioactive force and chronos relax and some ugly gradients and then Tori (only shows when you go on a server and 2 people are in the middle of a game) has a dark duke on the head and vampire relax and gaia force or something. screenshot: http://prntscr.com/4junxi
is this a update or something or why is it this way :|?

Sometimes their customs get messed up, manually updating them will fix it.
You can also make the custom/uke and custom/tori folders "read-only" after you download customs, this way they won't be changing anymore.
