Yes. What are the odds of getting, out of a potential pool of 560 random sites, 3x Enchanted Tower in one province? Yet I saw that happen just the other day when Kaljamaha and I were playing a co-op game. Had 3 arenas in one game, though that was way back in DomPPP.

Statistical anomalies happen sometimes, there's a reason why the concept of data outliers is fairly important in science. One instance does not a proof make. It could be that in a specific game, the random seed for some reason gets "stuck" so you would get more than one of the same item. But I don't think so.

If there are three categories of items available, with a specific event giving a higher probability for one class of item, getting several instances of that event would reduce the pool of potential choices, lowering the odds of getting the same item twice. Got two or three berserker pelts myself in one game, for example.

So I'd say it's random, all right.
