I think I'm quite old myself but fine. I just have 1 caravan in charge of my 80 steward 80 trade companion. I wasn't earning a lot from it either, (considering what I was earning from all my cities and castles). It had like 90 men strong, but after the update, the number descended to 30 and got captured right away, and then again.
I know EA, I don't have any problems with bugs, I don't like the fact that they changed something for the worst, it should be the other way around.
