So over the last few days Ive gotten several notifications for forum responses to some of my posts that when I click on the notification to be taken to the thread and respond are instead taken directly to the wiki page of the game/concept the thread sas about. I'm currently running Win7 64bit on the latest version of chrome.
Are you clicking on it in the drop down or on the notification page itself?
If the hyperlink itself is wrong, I'd assume it might actually be a server side issue, but have you tried clearing your cache to see if it's something old gumming up the works on your end?
It seems to be working for me in both places (Win7, Chrome beta latest).
Yeah, this has been happening to me for the last day, as well. It seems to only be when a post is linked to a wiki page. It goes to the wiki page instead of the actual forum post.
So, there is a thread about Dark Souls, and when someone replied, the notification just linked to the Dark Souls page.
I had three notifications today for replies, two in a Dark Souls thread and one in a General Discussion thread. From the drop-down menu, the two Dark Souls notifications will link me to the Dark Souls wiki instead of the relevant thread while the General Discussion notification works as intended. Link to offending Dark Souls thread. Links offered by offending notifications.  
So this just happened to me. Notifications have been completely broken for me since the site update, but today I got a notification and it brought me to the wiki page for the threads topic.
Well, they werent completely broken. I was notified when someone started following me, but not for comments.
Can someone @ me to see if Im getting notifications consistently now? Wanna make sure it wasn't a fluke.
