Found out the answer, initiate "marvin mode".
type "hero export", and the game sends a file to your save folder (you can change your attributes this way as well).Close the game and open this folder
with notepad, at the very bottom you find "sleep mode =0",change the 0 to 1 and save.Start the game ,enter marvin mode
then type "hero import", the game then uses the save file you have just altered. Problem solved
