My impression is that moving off the map is not really moving. It's spending a movement point to trigger an effect to take a figure off the map. This effect is usually part of the quest description. In some quest there are doors or tunnels that can be passed by spending a movement point. Moving off the map seems similar in this respect.
Thus, if Grease Trap is triggered when a hero enters the last space of an exit tile, he would hit the wall. Interestingly, this interpretation would also mean that a hero cannot move off the map with effects such as "move up to you speed" or "move X spaces".
However, if this is true, is spending that last movement point considered to be an interrupt? Does that mean that you cannot leave the map if the exit tile is occupied by friendly figures as you cannot interrupt movement on an occupied space?
Thoughts?
