4x more Barbarians spawn when trade route is plundered.

[Caanite]

I am playing as Venice and barbarians started raiding my trade routes. I got fed up so I started attacking them. Then suddenly 3 galleys and a brute just spawn out of nowhere. Is this a part of the game or is it a bug? The barbarians appeared as soon as they raided my trade route.

Barbarian spawn more units when they pillage trade units

 

[Caanite]

i know that by they spawned more than usual. is the number randomised because four units from one trade route is a bit much

What a coincidence... just 4 hours before: http://forums.civfanatics.com/showthread.php?t=514318
The very same thing happened to another guy?! And as one can see on his screenshot it wasn't one but 3 caravans in one turn, resulting in 3 extra units spawned.

THis is extremely plausible, because pillaging a caravan doesn't cost any movement, they'll automatically be pillaged when they try to walk trough a barb unit and since the barb is next to your city there is a high chance that all your caravans will try to cross that tile.
