Ahh, you misunderstand me. I was talking about Earth's one. You know, where they went before fighting Cell? Got destroyed when Piccolo wrecked the door.
To be fair, they did say it was a new Hyperbolic Time Chamber, maybe it doesn't have the same rules as the old one.
OT: There are even more plotholes and inconsistencies in DBS. Why did Shenron have to revive Mecha Frieza in pieces, when he had no problem whatsoever to revive people who were completely annihilated before? Pan is born WAY too early. Where is Bra? Why does Bulma look like 20 again? Why do Goten and Trunks still look the same? These are the ones that come off the top of my head, there are even more. Now add the terrible animation and lazy writing in general and you the mess known as Dragon Ball Super.
