This is related to (the same as) this bug: crystalBallMonster incorrectly reset
In some cases, "crystalBallPredictions" will be incorrectly reset to nothing (the property will be cleared) when the prediction is still true.
I believe this happens when the prediction gets set during a free turn (such as a free banish) and the next single turn is in the same location.
This is with r26269
In the example below this happens (all in The Haunted Library):
[22] fight banshee librarian, prediction=writing desk
[23] fight writing desk, prediction=banshee librarian
unequip the crystal ball
[24] encounter a banshee librarian anyway, use a no-turn banish (BOWL A CURVEBALL)
crystalBallPredictions is reset (now it is blank)
equip the crystal ball
[24] encounter a banshee librarian
The only way this last encounter should be possible is if the banshee librarian is still the crystalBallPredictions (because banshee should be banished)
