|Bribe each fraction. Or just do missions for them. You'll get it in no time. If it glitches, return the mood to neutral and re-gain the bar. If it does not unlock join someone's co-op game where the mood is at the maximum. You can also unlock it that way. If all else fails, start a new game and rush the story missions. Once you get to the faction that glitched, bribe them.|
IF all else fails, load up the save while playing off line. It seems to be an issue with EA's servers. Thanks Wii187 or the tip.
