"Last Post" in forum links to start of thread?

[wishtheend]

I've tried a search on this, but couldn't find any thing yet.

In my forum directory the "Go to Last Post" button works correctly, but if that same button is used in any of the actual sub forums, it links to the first post in a thread rather than the last?

Any suggestions on where to look to correct this?

Here's a link to my board:

Thanks in advance for any help.
