Why don't more people actually read the news on the front page?

Indeed. Also, we'll be posting an update to that blog very soon.

Yeah not these ones, the ones they aren't telling people about. If my mechanic changed something on me without telling me, I would leave him for a new one.. Looks like it's time to get a new game lol.

The nature of hotfixes is such that posting the notes in advance isn't practical, but I try to ensure that they are updated as frequently as possible. Still, there's a lot going on and they take time to compile. As stated above, an update is coming.

Now with updates:
