1) The events "Sir, the enemy is gaining the upper hand in the war. We have lost 1 Engagement Point" - or it's equivalent for winning - seem to be mis-worded, since AFAICT the effect is to raise or lower morale, not EP.
2) I've noticed this happen a few times before playing the Brits, but here's an American example (to be found in the Nov 77 turn in the attached savegame): Message appears saying supplies have arrived, "latest shipment from Hortelez & Co" or whatever the text; clicking the event will focus screen on a particular location (in this case, Philadelphia). But lo and behold, a new supply unit there is none! My theory is that in some events the supplies sent are actually ice cream, and it melts before I get to use it. But maybe it's a glitch?
