The Gearbox Software Forums have a thread about the new update that went live yesterday for Aliens Colonial Marines, eventually reporting it was fixed to sort out the user complaints the new version generated. In spite of the patch notes containing only two entries ("Added toggle for film grain filter" and "Increased security to address cheats and exploits"), the patch caused problems for many users, including missing downloadable content and an inability to use legitimate ini tweaks, attributed to the anti-cheating changes. This lead to Gearbox pulling it from Steam entirely, saying: "The update will be temporarily removed from Steam while the team investigates the corrupt DLC error and works to resolve that. More details as I have it." This is followed by a wee hours update saying a new version of the update was rolling out, and the subsequent posts indicate this has solved the reported problems. Thanks Guille.
