I've noticed that when snake collides with object (happened with cliff once afair) he stops moving just to teleport and bite the player after a short time, anyone noticed that also?

Yes, in both the last world and the current world I have been a victim of this problem on a few occasions.

Additionally, my character will sometimes run RIGHT OVER a snake when using Bullrun. It has happened many times and I am certain that it is either a bug or a simulation of a failure to hit. I'd be interested in any information clarifying this as a bug or as an acceptable behavior.

I too have fallen victim to ninja ghost snake. Snake becomes invisible and teleports to bite character who is running away top speed after colliding with object (cliff). Character much faster movement than snake, then suddenly snakebit.

I came across this last night, I thought he has stopped but I was running through rabbits at the time and i heard a rabbit pounce at him. I have a suspicion that they go invisible and continue to chase as he didn't reappear until I hit a river.
