Important question: do you disc before the first 60 seconds or after the first 60 seconds?
W3 originally supports only 60 seconds of lag and the time was artificially extended with some bot/gproxy hackery. So if it happens after 60 seconds there might be some condition in that mechanism we need to take a closer look at.
If you do not know please pay attention next time.
Anyway, I will release new versions of bot and gproxy with additional logging at lag screen so we can perhaps get a clue on what is going on.
