I was in bootcamp42 with my friends, and I got teleported to bootcamp2 along with one of my friends. Can someone explain to me what happened?

i don't know but this happens very often in racing too

Yeah, this happens a lot in bootcamp now.
And there are too many hackers, but no mods!

Here too, it's satellite server issues.

Sometimes when you play a room for too long, it will sorta "restart" and you will be teleported to another room
Or (I "think") if you are playing with -5 players, you will be teleported

No, it's not intended to do this at all.
Anyway Lemo actually answered this and this is no longer happening.

As of yesterday this is definitely still happening. Do you know something I don't?

Ah, truthfully no; I was left with the impression it had been resolved. My apologies for the misinformation.

Bummer. I was hoping you were saying it got resolved between yesterday and today.
