Answering Machine bug

[Soom]

I've got all of the cassette tapes from the vanilla game and the achievement has not popped. I checked off every single cassette tape from the vanilla game so I am very confident that I haven't missed anything. I have also completed both dlc so I have a total of 61 tapes. Does anyone know what might be causing this to not work.

All I can say is that I had at the end 64 tapes – and the achievement...

...and for reference/proof:

Go through the list with a guide, long as u got all of em that's in the guide you should be good

I did check off each one and it did not work. This is because if you have the dlc installed it counts those tapes as well. Starting a new save without the dlc installed did get me the achievement though. Needed to do another run for the supreme jerk achievement anyways.
