What Does The FH Patch Do?

[Neowulf]

Now, if you read the subject line, you will see: I don't know what the patch does. I'm guessing it does something similar to removing glitches or resetting stuff in the files. But I'm not sure and I don't want to click on it without knowing. It's not just my curiosity: I accidentally installed Feralands.... Into my game. And I want to remove the stuff and I can't reset the textures and... To put it short, I want to reset my FH experience back to how it used to be. If you can help with this or tell me what the patch does, I'm accepting any answers. Just don't lie.

The patch pretty much just updates your game by downloading all the new features. It's a lot easier than re-downloading the whole setup all over again. The game setup has everything the patch includes so there is no need to download the patch considering there are no current updates to the game.

You can download the setup here (attention, it will start the download as soon as you click it, for these people that are curious...), and replace. Feralands is a SEPARATE game, you shouldn't replaced it. Well, at least you hav' a setup, right?
Also, FL already has the most recent update. So, nu worries.
