So i just spent about an hour taking down the slaughterhouse 3000. And after FINALLY finishing it solo (i don't like playing online) i was met with the infamous enemy out the playable map bug. Then after trying grenades/rockets to no avail my game crashed and shut down (ps4).

Ive read up online that homing grenades help but id like to get everyones opinion as i dont want to waste another hour to no result. I literally only need to do 2 COS for the platinum trophy.

Also i read that using photo mode and melee works but the enemy spawned on the second floor and camera wouldnt reach. Thanks in advance.

Edit: or any advice for getting through it quicker?
