Due to a discussion in the Steam forums, where another user said he couldn’t find a bug report tool on your website, I recognized that your pinned topic about bug reports still refers to your website, instead your ingame bug reporting tool. I couldn’t find a bug report tool on your website neither, so I think it’s gone as there is the ingame tool?
Guess you should update your pinned topics in the Steam forum to prevent confusion for bug troubled users there.
