Hmm it's really weird, since it just doesn't happen for me.
Which desire specifically does it happen for? Or if it's several, can you name me one?
I've only tried it with lanch thus far, but even to use the portal, i noticed that when the main character's exp was ---- (i.e. the max) the portal wouldn't work. I had to use the rock book to lower my level to 89 for it to work, so maybe the desires levels also have to be reduced? (i was doing this with the desires levels being 99 so their experience were all -----)
