Pokesav Platinum Issues

[furion]

I suspect I've corrupted my save file, or perhaps the ROM itself.

I use an r4 SDHC, with platinum rom, I'm not certain which version firmware.

First i moved my party pokemon into a box. I copied my .sav file from my microsd card and attempted to edit it, using pokesav. I changed a few EVs on giratina in my box to test, then saved over the file on the microsd card. Once I loaded up the game I found that all my party pokemon that I had moved into boxes had completely disappeared. Worse, after erasing that .sav file and trying to use the backup, I find that anytime I move a pokemon into a box and save, when I reload that pokemon has disappeared completely.

So, anyone know what's going on?
