Crashes if Altitude from one playlist reached but otherwise can't resolve

[schpoorky]

If any playlist specifies either a minAltitude or a maxAltitude, once the conditions are satisfied, the game will crash if that playlist specifies a prerequisite which doesn't match the current active vessel and another playlist does, provided this matching playlist isn't rendered invalid at the current Altitude.

Example: While at Kerbin I had gone smoothly from InSpace playlist to InAtmosphere playlist, until hitting 60000m, which was the minAltitude for my Mun playlist (to avoid rapid reload crash while moonwalking). Removing the Mun playlist fixed it.
