I DID have an issue, IIRC, because of a typo that capitalized "Jerusalem" when it should have been "jerusalem". You might want to check that. Not at home comp, so can't give you the exact code I've got.
Edit: Found it! Sometimes the old memory functions after all!
In campaign_script.txt, change:
Code:
;-------------- JERUSALEM_INVASION --------------; 1100 against Prussia
monitor_event FactionTurnStart FactionType any
and I_TurnNumber > 13
add_events
event emergent_faction Jerusalem
date 1100
end_add_events
to:

end_add_events
Bet that fixes it!
