So one today, I was chilling on PPNL's CC server. I was admin level 5 so I could add and remove bots at my free will. Two of my friends reported that they have taken on weird abilities such as turning when not touching the keyboard, autoaiming at nearby hostile hitboxes, and evolving when getting a kill. So I was confused. So just for my luxury, I decided to add a bot named "IndigoIvory" on the alien team. The bot spawned, but didn't kill me, but it span in circles. I was wondering what was going on until the bot said "wtf?". I was confused, so I looked at the scoreboards. One of my friends left without warning. I then realised something. My friends are both bots. They took on bot characteristics such as what I mentioned before. So, my friends are psyicaly humans, but console sees them as bots, not players. So, one of my friends left and I added a bot. That bot was my friend again. I pulled him out of the main menu suposedly, but I couldn't pull them from other servers. When nobody but me was on the server again, I added a bot. This was an actual bot this time. Later, my friend connected and joined in the same place that bot was and that bot left.
TL;DR
Console sees my two friends as bots and controls some of their abilities.
