Hi guys, I have like 400 hours in Monster hunter 4 Ultimate, and in the last 50+ hours im having hangs in the game, each time more often, loosing hours of gameplay, since i have the game in 3DZ format inside my gateway, and when the hang happens i need to turn off my new3ds. Anyone knows what is happening??...maybe my microSD is fragmented or something? i have a Sandisk Ultra 32GB class 10. maybe is better to change my save to a CIA version of the game? many thanks in advance.
