I encountered some bugs with my AI buddies, but this wasn't mentioned in the know issues:
-Ai teammates don't shoot at enemies in some vehicles like: CV1, Path Watcher like vehicles....
-They sometimes auto respawn or revived by themselves after dying
-They don't even try to revive player when vehicles is catching fire and let you die...
-They can't base jump
-As shown in the Ai trailer, they never go to the back (trunk)of Path Keeper vehicle no matter the circumstances...

Hope these get fixed in the upcoming TUs
