I ran a short story a few months ago when one of the magi had Special or Story Event during an experimentation. He was experimenting on a Mentem spell, so I had the magus suffer from nightmares and sleepwalk to an unexplored part of the cave network under the covenant, involving something about the magical aura of the covenant (the story is here).
Personally, I find such stories interesting. Not a burden at all, particularly in a PbP format. Certainly be more difficult to handle during a tabletop game.
