escape mode bug/error?

there's one game of escape mode that I've played were I don't see any doors, and I can pass through it. However other players can see the doors which means there's really a door but it's not visible to me, sometimes I see it, sometimes I don't.

it only happened to me once though..
it's like a hack where you get pass through things, but it only happens on the door..
(I don't use hack) so it doesn't make sense. It's probably a glitch or something like that..

I didn't really do anything, I just joined the game and it's already like that.
does anyone had this situation before?

not that it bothers me, but if this happened to me then other player could have this experience as well.
