I think if you open up the league page multiple times while sim is in progress, the games won't be hidden. I wanted to watch the playoff games without seeing the results but when I went to the league home, the results were shown. Has this happened to anyone else? I was thinking the league results should always be hidden after each sim until you press unhide for that week.

Edit: I just refreshed the league page and the results were hidden. Not sure why it changed.

You might make sure you have the 'remember me' on for your login - the results are not hidden if you are not logged in.

So I went to check on the league's sim but it was still in progress. I check back an hour later and the sim is done. I'm on the preview page but I notice that it doesn't show the 'game results hidden' message, meaning the results are being revealed for some reason.

Edit: I don't know man, the 'game results hidden' message showed up like 20 minutes after I posted this. Don't know why this happens.

I think the part about going to the league during the sim might be key. I have had this happen to me twice and I am pretty sure both times I went to league while it was simming.
