I really thought I had it for the longest time..I must have been mistaken :/ I would kill for a counter because I bounce -everywhere-. I don't walk, I pogo.
I deny that WalruZ! :) No, seriously, the achievement itself was not broken. We just couldn't be sure with some people's help case reports about it (and a few other achievements, as you probably saw from forum posts) until we had some of our tools to check in order. But, it's working. (Also, some other achievements weren't working for sure- the completist ones, which we got dialed in several days ago.)
