I noticed that the chapel is not in the rooms drop down menu for the construction table.

Thanks, I've passed this on - unfortunately it's not something that I am able to fix myself. In the meantime one workaround is just to change the URL manually. Note that when viewing a certain room, it loads the page:

So to get the chapel, you could do:

 

 

http://www.tip.it/runescape/tables/construction?table=Chapel

 

For the combat room:

etc. Hope this helps :).

Thank you for passing it on, and for the workaround.
