Mutant Mudds, which made it’s debut on 3DS in 2012, and has recently been updated to include the 20 ghost levels from the Deluxe version of the game.  This is likely some very good news for those who own Mutant Mudds on European 3DS consoles because the Deluxe version of Mutant Mudds was never released for Wii U in Europe.  Unfortunately for everyone, the new update has caused some issues with save files after the update is installed.  For some gamers diamond counts may be off or the ability to switch between characters can be lost.  Renegade Kid is aware of the issue and is looking into it.  They will likely release a patch to permanently fix the issue but for now, the save files can be restored by simply beating the first ghost level.
