Please if you find something wrong with the game that need fixing, please email email@example.com
and they'll see what they can do. The DoctorWhoTEC page on twiter instructs you to do so. The Discussion board is a nice place to see if anyone else is having the same problems, but it is probably not monitored for bug reports in the game. It's set up by Steam, not the game developers. My understanding is when the game was released on PS3 there was a patch released to fix some bugs, and it's possible they never looked into seeing if the PC version had the same problems. I've already emailed almost a week ago about the crawl and achievement problems. A day later they replied saying they are working on the problems, and a patch will be released shortly, though there still hasn't been. It's possible they are still waiting for more bug reports and information on them before they send anything out.
