Yesterday, i encountered a weird bug. For one of my 3ds I have a Gateway Card with a Smash.3ds file to play. I wanted to have updates and DLCs (which purchased on my New3ds), so I loaded them down with CIAngel and installed the latest update (1.1.5) and the latest DLC from the latest wings.json (which are Ryu, Roy, Lucas). There wasn't a problem. Then I made out of the 3ds file a cia and installed it to my other 3ds. I tried to install the same DLC file to this 3ds and it gave me the invalid signature error. The update worked fine. Then I started Smash on the 3ds I got the error from. I was very surprised to see that all the DLC was already unlocked :o But my Gateway 3ds Cloud, Bayo etc. weren't installed. Is there anyone who has an explanation ?
