There are no bots that can make you walk through walls or disappear. This happens because of hardware problems with all AMD hardware. PS4 is not immune to this because it uses the same hardware from the same manufacturer of computer graphics cards. I know this because I used to run this hardware, and it did the very thing that you're describing. Lag is also very guilty of this too, because your PC or PS4 isn't receiving correct data from the server. Reporting of player position is handled server side, not so much client side. If that weren't the case, everybody would be doing it. If bots were the cause of these issues, then you'd see everybody flying out of zone boundaries, and it doesn't happen. There isn't a bot around that can influence the operations on server side. Just google search this crap. It's all out there.
