When you have engineers clearing mines or barbed wire, after you click End Turn and the only thing that happens during the AI turn is indirect artillery fire, then the map is positioned to the engineer units but there is no visible message as to results.
I've attached a save which when you hit End Turn shows the quirk.
Yes, that is known and we may well get round to fixing it one day, if it really is a bug. (Messages are not displayed for many unspotted units, as it gives an advantage to the human player. In which case the centring on the cleared hex should probably go, but is likely in another bit of the spaghetti).
