I recently reinstalled

on my laptop.
I have lost my old savedgames so I wanted to make a new game but straight to the Battlefields Act.
So I just renamed a few folders: Act5 to Act1 and the Bd_act5_start to Bd_act1_start, and vice versa.
So when I started the new game I started in Act 5.
All goes wrong if i try to enter a rift, it goes through a almost instant loading screen but I end up back in front of the rift.
I can't remember if you need an item to go through rifts in act 5
or if you actually needed to find those battlefields keys in previous acts.
