Raptor agrro range

[dude]

I was out in TD the other day on my Wizard and i ran around the Raptor islands one time each no problems on my way back between (I was running back to the little sandbar to kill the single spawn again) and i picked up a raptor on the way thru, when I got to the sand bar the single raptor agrro'd me also. I though this was strange, did i get friendly agrro or something? Your probably wondering why I didn't just kill them, I couldn't cast on them as they where in the water, and I had levitation on not dead man floating, wish i did though cause I wasted a batwing and a sow pot just to end up back in Thurg bank. So I went and killed some giants and got a few frost giant meats to make some nice stat foor out of. So anyone think it was just friendly agrro?
