DJMM fight, but something's not right | FNAF: Security Breach

Since one of my endings was bugged, I started the game over again and tried to reach my missing ending as fast as possible. Because I went so fast, multiple bugs ended up stacking on top of each other, resulting in this boss battle being quite different from what it's supposed to be.

Here is a list of things that were not right in this boss fight:
-At 0:15 I get into Freddy. You're not supposed to be able to bring Freddy into the arcade.
-At 0:43 we can see Chica isn't broken and at 2:07 we can see Monty unbroken as well. Even though to get to this point in the game, I should have defeated one of them.
-At 0:52 we can see DJMM crawling on the walls before he has been activated.
-At 1:17 I angled myself in such a way that we could see DJMM despawn.
-1:46 Freddy is wall
-At 1:53 I can just walk through music man thanks to Freddy.
-3:09 ok when did she have time to get downstairs?
-4:47 glitching through DJMM again thanks to Freddy

Lastly, if you compare my Freddy battery at 0:20 with the battery at 5:20, you'll notice it never went down. Infinite battery.
