Comment Limit? ("invalid token error")

Is there still a comment limit on this site? I'm now getting an "invalid token error" when trying to reply to a comment that was asking me a question. I've posted around a dozen comments total in the last few days, which is more than usual, but not excessive at all in my opinion.

This new comment system has been extremely disappointing. The previous system worked great, the upvotes worked properly, you were actually directed to the comment when clicking the link in an email or the notification on Gamespot, and we weren't restricted to a limited number of comments. Why did Gamespot change commenting systems in the first place?

If users are actually this limited in the number if comments we can make, it's likely that the community will fall apart as people go somewhere else to have less restricted discussions.

If you look down at the other topics below, you'll find this bug has been reported a few times. It doesn't seem to be a limit because if it were, it would explicitly say you've reached some limit. There's just many problems with the "token" system it seems.
