Keep in mind this means ALL mods from the article. Personally I don't care about achievements but it kind of leaves me miffed and this decision. So apparently according to a couple different sites I've visited info was leaked that mods will disable achievements in the next actual update. I'm not in the beta so this isn't breaking an NDA or anything on my part by sharing it. To moderators: I'm not sure if this is details that people weren't supposed to know yet but it's been publicly leaked.
Disclaimer: Take this with a grain of salt, I can't personally confirm this but I'm posting it just to make people aware.
