I wandered into a tallbird area and of course they all got angry. I ran away but one tallbird would NOT stop chasing me. I didn't have its egg, it just wouldn't let up. (I thought they would eventually drop off even if you did have their egg) But nope. Since it was early days I couldn't stop to eat, gather, I could do nothing but run, I ran all day long but eventually died.
Steps to Reproduce
piss off a tallbird and then run
