I truly appreaciate your mod. it helps my single player game better than ever because of default bots have slow respond. I don't use all features in the mob because I don't want to ruin my experience and enjoyment about the game, so I only turn on some features to let the bot survive and support me through out custom campaign.
overall I played the map again and it has some minor mechanic changes. about the finale, they are not random if you are playing from the motel arc. it's based on your action in the area which has indian runner, annie's bar and motel. I don't know the mechanic. I just did full options and got the good+ (I assumed) ending.
