Swaping MP and SP savegames

{First of all I should say that I haven´t proved detailedly what I will say so I will not assume any failures on your systems }

Tired of playing SP and having to include NPC´s that you don´t like ??
Tired of playing MP and having to bear its incredible slowness ??
Well, I think I have the solution for your problems !! As I´ve found out, MP and SP games are exchangeable (or whatever it is said)!! Simply take the folder that contains the desired savegame and take it into the 'save' or 'mpsave' directory!! I have done it and, at least, it could load the games and I was able to include new characters into my SP.
VERY IMPORTANT !!!: I have done it with a SP that I was playing with a single character (no NPCS). So if you are going to take an SP to MP, I recommend to remove all the NPCS first. Anyway, I´ll prove with NPCS and tell you what happens (I hope nothing ).

BYE !!!

PS: if this is obvious and known by everybody, I beg you pardon for looking so idiot.
