bugfix: too many effects generated on framestep

This fix works for replays played from the replay browser,
and for normal play with framestepping.

It does not work for loading the user savestate: Effects will
probably be drawn at least once. I'd have to save the entire effect
list with the user savestate, which would be overkill right now.
