Caped Bullet Kin able to fall down pit. AI bug?

[Vivi]

So I was in the 3rd Chamber (The Mines), and found one of the incredibly rare and hard to find Bullet Kin with a red cape around their waists. I shot them once without realising it, but left them alone afterwards, going for the other enemies whilst the caped Bullet Kin was offscreen. I then heard the sound of an enemy falling down a pit, and sure enough the bullet kin was gone. He had likely walked forward into the pit that was between the two of us at the time. In a salty rage, I exited the game immediatly and began making this thread. I am certain I did not knock that Bullet-kin into there, that they had walked in there on their own. Most ordinary Bullet Kin I've seen usually walk around the pit.

Here is a copy of the output log, put in pastebin for your convienience. [pastebin.com]

I can confirm that enemies sometimes walk into pits of their own accord. Most of the time the enemy has to be hit at least once, and it doesn't have to be anywhere near the pit at the time (and it's definitely not the knockback from the shot that pushes it in).

Sorry to hear about your caped Bullet Kin enounter :/
