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.
I noticed it with this comment. Sometimes it’s the correct post to start with “Planning on building a PC, anything I should know?” but other times it’s a random post, and sometimes the post will randomly change while the page is open. This time got one that says “FTC will try to block Microsoft’s acquisition of Activision Blizzard” and then while the page was open it suddenly switched to “Megathread for Reddit Blackouts and News - Week 1”. Not sure how to find the erroneous post ids but here are screenshots. The vote count also goes absolutely wild, rapidly changing with random numbers.
