Example: The newest unread post is 3824118 on topic 372475 accessed using https://scratch-mit-edu.ezproxyberklee.flo.org/discuss/topic/372475/unread/ .
The post is removed, so website redirects to https://scratch-mit-edu.ezproxyberklee.flo.org/discuss/topic/412/?page=2766#post-3824118 , which is dustbin topic post.
Solution: The https://scratch-mit-edu.ezproxyberklee.flo.org/discuss/topic/372475/unread/ redirects to last avaliable post before deleted one, which is https://scratch-mit-edu.ezproxyberklee.flo.org/discuss/post/3824038/
