Has anyone else had this error? I've only been replied to once so far so I can't see if it's just a one-time bug but if it happens again I'll try to remember to edit this post to confirm it.
When clicking on my messages inbox after getting a reply notification I was able to read the reply sent to me perfectly. However clicking the upvote button did not register a +1. I went directly to the thread and was then able to upvote with no issue.
I am using Firefox in case that helps.
