Here's an example.
First, take a look at the official DB entry for Andariel's Visage. Note that only one random magic property should appear on the item, in addition to one of strength, dexterity and intelligence between 112 and 129.
Well I just found an Andariel's Visage which has 171 strength — well beyond the maximum according to the official D3 database. It also has the random stat of 26 vitality, so it can't be an overlapping strength affix (is that even possible?).
What's going on? I suppose the database definition could be incorrect, but I swear I've seen this happen before.
