So, after a while I returned to ME =) and I decided to move to another place on my old map. And this new place has quite a number of barbarians, who are constantly rushing into me, so I've built a small palisade fort, with 2 wooden gates. In the beginning it was fine, barbarians were attacking the gates, I was killing them from time to time, but one thing was strange - gates didn't receive any damage. Or at least appeared to. So, here comes first question: 1) can AI damage my building? And now another strange thing happened - gates just got broken. And just before it the durability was almost at maximum (I didn't finish building it). So... 2) any idea why this happened? And a final general question: 3) How do you deal with barbarians? Is there any way to protect my buildings?
