milkyway2heaven: So I was stuck on Ghost Dance for quite awhile. As a matter of fact, 3 days. On easy difficulty. The reason being is, I'd save all hostages and kill all terrorists. "So whats the deal?" you say, "That's how you beat it!" you say...- well that's my problem. I noticed with several attempts at this mission this mission is littered with bugs. Terrorists showing up on the radar but not actually there, and some appear to be in walls. The biggest problem is even if you spare some terrorists, you can rescue all hostages and still not get the passing screen. I know it's an old game, and I know glitches can still occur. But this was actually game breaking for me. I couldn't win at all.

So I dug around. And I found out, the numerical value for the victory condition for this mission is Rescue "ALL" hostages. ALL, meaning not a clear defined number. My play through's show I've only rescued 4 hostages and killed all terrorists(if im lucky and can have them spawn correctly) even though the winning screen shows 5. So wheres this 5th hostage?

Well what i did was I went to C:\GOG Games\Tom Clancy's Rainbow Six\data\mission, found all the victory condition files(shortened as VicCondM#(difficulty) ) and altered the condition of Mission 5(ghost dance) from:

Condition 0: Rescue the hostages
HUMAN_CLASS_CONDITION HOSTAGES
DESCRIPTION VC_GEN_RESCUE_ALL_HOSTAGES
GOAL_TYPE PRIMARY_GOAL
HAS_REACHED_EXTRACTION_ZONE 1
NUMBER ALL]
RESULT SUCCESS

to

Condition 0: Rescue the hostages
HUMAN_CLASS_CONDITION HOSTAGES
DESCRIPTION VC_GEN_RESCUE_ALL_HOSTAGES
GOAL_TYPE PRIMARY_GOAL
HAS_REACHED_EXTRACTION_ZONE 1
NUMBER 4
RESULT SUCCESS

This means instead of ALL Hostages, I'm rescuing 4 Because that's all I can do. If you experience any issues like this with other missions, whether it's bombs, terrorists, or hostages...this will help.

Sorry, I'm not sure if this is public knowledge. Just letting others know
