I already posted the same question in another board but I'm not getting any replies, nor have I found a concrete answer concerning my question (in the other message boards or the internet). Since editing your main pawn stats via the save editor will no doubt corrupt the pawn. My question is that; if I were to spam the exp option on the trainer to level up my pawn without touching its stats, will it still be corrupted? A swift reply is much appreciated. Thanks in advance.
If by corrupt you mean your pawn gets banned, then yes editing stats will not work. By leveling with xp, the stats will be legitimate, so it's unlikely to get your pawn banned. It's best just to set your game to offline and you can do whatever you want without needing to worry about it.
