Thanks for the heads-up from some of the players: there was indeed a glitch preventing some of the Summer Sideshow achievements from working properly which, of course, made it pretty tricky to unlock Steampunk Mr Foster. Should all now be working fine – server admins will need to update servers, but all clients should update automatically through Steam.
And, we are happy to say, the Steampunk Character Pack DLC is also now available (http://store.steampowered.com/app/35425/) to buy and to use if you pick it up with tickets in the Prize Booth (http://store.steampowered.com/summersale/prizebooth/). Apologies again for the delays – remember, we are extending the Event through the weekend of 23/24 July due to the late start! make the most of it!
