I'm using an Acekard 2i and an untrimmed Picross 3D ROM. I've completed all puzzles so far without errors (369 stars and solved all 19 puzzle packs) but I didn't make this topic to brag about it. I'm having issues regarding the latest Puzzle Pack. I'll enlist it chronologically so it would be clearer. Oh, and before downloading the puzzle pack. I had 3 user saves in the game and my downloaded puzzle count is 99/240. - Downloaded Puzzle Pack 20 without fail. Turned DS off to play another game. - Played the game again and the third save file has mysteriously disappeared. It also appears that Puzzle Pack 20 has not been included in the Downloaded puzzles but when I went to WFC to download it again, it says that I've already downloaded it (shown with a tick). Downloaded puzzle pack again. - Deleted some puzzles (the whole of Puzzle Pack 1) as I thought it was a space issue and that the game can only contain 99 downloaded puzzles. Left with 87 puzzles. - Played one puzzle from the pack. After completing the puzzle, I got a message along the lines of "Cannot save. Reinsert game cartridge". Restarted my DS. - Booted up the game again and now, 2 of the 3 user saves have mysteriously vanished! Mine is still intact. - Again, after checking the downloaded puzzles, the same thing happens again - Puzzle Pack has "not been downloaded" and the puzzles I have deleted have reappeared. :/ - Tried re-downloading the Puzzle Pack 20 but, this time, the game hangs up everytime. Anyone know what's up with this?
