Not sure if this is related to the servers getting hammered by all the new traffic, but I noticed when I look at a reply in my inbox and click the star to see the context for the comment, the post that is shown above the comment is totally random. It is not the post in which that comment was made, and the context that is shown changes each time.

Hopefully I did a decent enough job explaining the issue, or at the very least others will be able to replicate it.
