One more thing: Have you checked if the functionality of your event block is also affected by the other event blocks of the original script and vice versa (depending on the order)? From my understanding this should be the case as long as you have empty status variables in FetchCharacterApplyStatusData (so the event block will always return the catched status to apply it) or two FetchCharacterApplyStatusData events for the same status (so two events interfere).

You probably have to add your resist code to every existing FetchCharacterApplyStatusData event (if you want to regard this status) and create new events for your statuses that aren't regarded already.

Example for the FROZEN status:

Code
EVENT CharacterSetFrozen
VARS
	CHARACTER:_Character
	LIST<STATUS>:_RemoveList
	STATUS:_Result
	FLOAT:_MagicArmor
ON
	FetchCharacterApplyStatusData(_Character, FROZEN)
ACTIONS
	Set(_Result,FROZEN)
	ListClear(_RemoveList)
	IF "!c1&c2&c3"
		CharacterHasTalent(_Character,Raistlin)
		CharacterGetStat(_MagicArmor,_Character,MagicArmor)
		IsRandom(_MagicArmor)
	THEN
		ListAdd(_RemoveList, _Result)
		Set(_Result,null)
		StatusText(_Character,"Effect resisted by magic armor")
	ELSE
		ListAdd(_RemoveList, CHILLED)
		ListAdd(_RemoveList, WET)
		ListAdd(_RemoveList, INVISIBLE)
		ListAdd(_RemoveList, SLEEPING)
		IF "c1"
			CharacterHasStatus(_Character, MAGIC_SHELL)
		THEN
			ListClear(_RemoveList)
			ListAdd(_RemoveList, MAGIC_SHELL)
			Set(_Result,null)
		ELIF "c1"
			CharacterHasStatus(_Character, BURNING)
		THEN
			ListAdd(_RemoveList, BURNING)
			Set(_Result, WET)
		ELIF "c1"
			CharacterHasStatus(_Character, HOLY_FIRE)
		THEN
			ListAdd(_RemoveList, HOLY_FIRE)
			Set(_Result, WET)
		ELIF "c1|c2"
			CharacterHasStatus(_Character, NECROFIRE)
			CharacterHasStatus(_Character, HOLY_FIRE)
		THEN
			Set(_Result,null)
		ELIF "c1"
			CharacterHasStatus(_Character, WARM)
		THEN
			ListAdd(_RemoveList, WARM)
			Set(_Result, CHILLED)
		ENDIF
	ENDIF	
	RETURN(_RemoveList,_Result,null)
