Jack spawn bug?

[Mamekuma]

I've played this game to death on the PS4, and I bought this game a few months ago on sale to replay it with better framerate and M+KB support.

It's been a few months since my last save, but my last reload placed me at the first save spot by the dining room, and I already have a gun--that means I've "killed" Jack in the garage already.

However, after moving down the hall, he broke through the wall as if it was the first time I've played the game. This isn't supposed to happen, right? The next time we see Jack is when he bursts through the bathroom on the second floor. I've never encountered this before--am I supposed to run past him? Is this supposed to happen at all? If I move around and go through the trap door in the cellar/closet again, can I avoid this "spoiler" until his actual respawn?

Thanks in advance

If you have a gun, it can also mean you reached the laundry room and picked up the Albert-01R from the box, since it is a permanent weapon after you beat the game once.
However, Jack despawns from the world when you move after a certain point on your way to the laundry room below the house. So, yes, it seems to be a bug.
Assuming you have the dog head in your inventory, you can just continue on your way. If you don't, then you didn't actually do the garage segment yet, check the garage. If it is locked and you need the knife, then go through the trap door to the laundry room, get the phone call, and get the deputy to show up.
