I jumped into a game starting on underground as defenders, and ran into the first objective room. There I noticed the doors appeared open but the generators were not damaged.

I wasn’t sure if this was a bug with the generators not appearing damaged or the doors not appearing, so I shot through it and killed an enemy (Hopefully they didn’t think I was cheating). However, I couldn’t walk through where the doors should be. After the enemy damaged the door generator the animation for the door opening played and it was actually open, and when we closed it it appeared as closed for me. Asking in chat it seems this appeared to no one else.
Edit: Ping was always less than 40.
