Not sure if this has been posted in the past or not but hopefully it will help some people that run into dead links. To fix dead links you need to move some things around in the URL however it is not very hard and is very consistent.
Basically you need to remove the subforum that the link was in which in this case is highlighted in red and replace it with the word "threads".

Then take the number that follows that and replace .html at the end with that number.

The end result should look something like this. I'm sure there is a way to script this somehow but I'm not very good at scripting these things.
