After posting a message to the topic https://board.flatassembler.net/topic.php?p=207995 and trying to open page 35 in the topic by using the link in the paginator I get redirected to a page with “No posts exist for this topic” message.

Yeah, it's a bug that pops up occasionally.

As of now there are 679 replies, but the counter shows 681. So the pagination thinks there are 35 pages, but there are still only 34 pages to show. Your most recent post is the last on page 34. When someone posts another reply there will then be 35 pages. But until Tomasz fixes it the count will stay off-by-2.

Moved to Feedback

In case it helps, while posting that message the redirection to the topic did not occur instead showing some error message of the same kind (post not found, not the exact text and AFAIR it was different from the message “No posts exist for this topic”).

This topic now exhibits the same problem.
