let me guess its when using the replay when you run out of time right? i put that in last minute. I had tested the clicking of the portal to go back in time and i did stop at 0.
It didn't stop at 0....Running out of time and accepting does this (I did it a few times to prove the point)
yeah. gave it a test and its the running out of time part that breaks it. once its under zero the portal button goes to pot :(
