So, after Hill Valley vanished I'm stuck at old Edna's place. I've got her out of the house and now I have to remind her of the time, when Danny tried to arrest her. The gametips say I have to play the incriminating recording for her.
Problem is, you don't have to take the recording device with you. I placed it back into the booth after Edna was chased away (while trying to find out what happened to Emmett). Because of this I don't have the recording device with me, when I visit old Edna. And I can't get back to get it.
