[SS]IV/EV/Stat Editting VIA PokeSav \. Confused./

[xmomox]

POKEMON SOUL SILVER

I recently just downloaded this amazing tool.

I'll get right to the question.

I put MAX 31 for IV and MAX 85 for EV or the other way around can't remember.

I then went to STAT EDITOR, and changed my attack to 85, my def to 98 etc etc. I save the file, load it up, all works well.

I have 85 att and 98 def.

I leveled up my pokemon and it went back down to like 45. What happened?
