Guys, I'm having a issue when I use the Save Editor...
I lost all my puzzle pieces and stuff (and some Streetpass Tags too, rip my 1000+ Tags, now I have like 600-ish) since I made a major mistake (deleted the wrong file -_- ).
So I exported my meet.dat (using the .cia version), opened it and unlocked every US puzzle except one piece (when I clicked to unlock all the US puzzles, they didn't show up at Puzzle Swap, only the Initial Set).
The problem is: when I import the edited meet.dat and open my Streetpass Plaza, it resets EVERYTHING like it was the first time opening the Mii Plaza (yeah, I need to pick the Mii that I'm going to use, type my greeting, select everything) and the Puzzle Swap is reseted too (I get the Metroid puzzle piece, the first puzzle of the initial set).
(Luckly, I made a backup of my meet.dat and could restore the 600-ish tags and everything else, just lost the Youkai Watch 2 Nintendo guy)
Any help?
(Infos: Old 3DS, using Luma, on latest FW update and Streetpass Plaza on 5.0)
