When our Alec told us wot he thinks about the Rising Tide expansion for Civilization: Beyond Earth [official site], he grumbled about a nasty bug in its overhauled diplomacy system – a very playground bug. When you declared war on someone, your allies might not back you up. “Yeah, go on, I’ve got your back,” they’d say, “go on, ‘it ‘im!” Then you’d ‘it ‘im. Then your pals would turn their backs and start whistling as a Siege Worm thundered towards you.
Relax! That bug is now fixed, thanks to a swift-ish hotfix.
