The wiki is huge and some parts are more up to date than others, depending on whether they're being worked on and who is working on them...
(There's around 250 pages in the Herocraft Wiki!)
So, Townships 3.0: The wiki content is on hold for another week or so because @Alator will be bringing in a number of changes/patches etc. When the code is relatively stable, we will update the wiki again.
Sorry, but I'm afraid there's no direct link between code and wiki content. In general, the wiki content comes after the code changes, except in a small number of situations where I (usually) am able to access the code before a launch - and the code is ready in enough time for this to happen.
Sorry about all the words. Just trying to show how things work in the real world of the Wiki. If you want to know how up to date individual pages are, check the page history.
