I've had 2 games like this now, where I pop in to check and it says new hut is built, but it isn't. The last game I had it happen with said it 3 times, and the second hut was only at most 40%. Do I persist? Keep it on the screen while they build so I actually SEE them complete these? It's frustrating restarting a tribe because the new huts don't really exist yet and so the number of villagers cannot rise.
