If yes, I politely ask to please explain in PM.

I just created a thread talking about a weird situation because I bought Elderborn and got an email saying I got it as a gift from GOG.

What should I do in a situation like this?

You mean this thread?

Yes, it disappeared for me. Is this a bug from the forum?
Thank you.

The forum is held together with chewing gum, so probably.

Thanks anyway. :p

Oh, and make sure to set the number of visible threads & posts to their maximum, in the "my Settings" button that conspicuously vanished from perception due to bad design.

Check the top of your forum listing, anything you make is automatically 'favorite topic' so you won't lose track of it. Thus it won't appear down with the rest of them.

Course maybe there's something else...
