So I have a major question that I have been asking myself for a long time now... I entered the playline and it started at like 72 hours. The time was going down kinda fast, so I figured I would get a chance to play that day. Well turns out, it was nightime and I had like 9 hours left, hoping it would go fast, and I had to go to sleep because it was like almost midnight. In the morning, however, it started over at 69 hours! So if I were to stay up.... would I be able to play it and it wouldn't lose progress? Sorry for the super long question.
If your computer went to sleep, that could be a reason why your timer reset.
Or while you were asleep, your playtime started and you missed the 3 hours.
I would suggest scheduling a PlayTime. If you want to get a PlayTime, you have to go on the PlayTimes page, and refresh your page at exactly 2:00 PM PST (Pacific Standard Time) and quickly get a newly added time. You have to be quick, only 30 people can get a certain PlayTime.
