I just saw this last night, it was really weird. His bull stood running in place, looking like it was low on health, but would not go any further or disappear. I could deal damage to it, but its life meter would not go down, and it continued to push back myself and droids.

Do you remember whether you were the server?

And whether the bull was created by you, a bot, another splitscreen player on your computer, or by someone else online?

Did the bull disappear after some amount of time, or did it stay there until the end of the match?

Also, has anyone else ever seen this happen?

I was online by myself (no split-screen), and the bull was created by an enemy Lonestar. I looked at it for a good 10-20 seconds (maybe even longer), shooting at and seeing if it would go away. It was at the very end of the match, and I had to go defend my base (which was quickly decimated), so I don't know how long it lasted or if it ever went away

I have no idea if I was the host, I doubt it since I think I joined up with this group for two matches before quitting after this one.

EDIT

Oh, and the enemy Lonestar was definitely a real person, not a bot. It was on PSN. I think this was the same Lonestar that managed to get himself stuck between our shield-wall and the scenery so that he could drop contact grenades without us being able to see him in a previous match.

Thanks for the additional info! We'll investigate this one further.
