He originaly left due to bugs ruining the game (Here’s a link about it I Quit (RichC) 🍺)
He did keep posting and browsing the forums until a year after (June 28 to be exact).
RichC (or rather his alt account) left the forums due to the direction the community was going as well as the game.
He didn’t like the idea of the devs implementing 2-2-2 for various reasons, but he really didn’t like what it was doing to the community. He didn’t like how people were pointing at each other saying they were the problem and arguing more and more creating the tribalism that we have today instead of pointing fingers at the devs who he viewed as the real problem.
