Hi all,
Yes, the team is aware of the problems mentioned and we are very sorry for this inconvenience. These are caused mostly by a super huge traffic going through GOG.com in the recent days - it was way bigger than we've expected :).
I think you should soon notice an improvement compared to the past few day, although the delays might still occur for the few days (though not as often). The devs already looked into this and we will be keeping finger on the pulse.
If you will continue experiencing bugs like post disappearing or a huge lag, please post here and provide us with as many details as possible (which topic was affected, the time when have you added the post, what happened... etc). It will help us greatly!
PS: Although this is maybe not the best topic for this, but Merry Christmas everyone :)
