I've found some bugs/glitches with ZAPT and I also have some suggestions/requests.
Bugs/Glitches: Bot Consumer's death explosions do not affect players, bot Leapers have trouble leaping horizontally, also, shouldn't bot Leapers crouch when they leap? After the Tank is killed, the moment the player respawns the director immediately reselects them to play as the Tank again. On rare occasions when the Jockey dismounts its feet are still invisible. Witches glitch out and walk aimlessly in a straight path if their target survivor gets killed before she kills them first.
Suggestions/Requests: Smashers have the ability to "stun" survivors when they charge into them, this is represented by the survivor in the sit animation and unable to move for 2 to 3 seconds. Zombies will follow Consumers until they spot a survivor. Survivors should be blinded when they are near a Smoker's corpse. Maybe there could be a "Random Zombie Spawn" that would spawn a zombie depending on how frequent they are in general, for example, a Standard Zombie has a higher chance to spawn than a Jockey does.
