I would say if any thing really kind of bothered me it would be side 4 which starts at 1:13:33 and it's very noticeable at 1:19 when Laurie is banging on the door screaming to get in.
I fixed this part and made a new wav file. The reason it was like this was if i didn't have side 3 and for together correctly then there was a slight audio drop out. So instead i moved side 4 just enough but had a small drop out between 3 and 4.I fixed this by mixing audio from the end of side 3 into the drop out, now you can't tell there was ever a drop out and side 4 lines up much better now.
