right.
but no patch notes. even o the official site. sounds liek they dont know what theyre doing.
Took a little to find it again, but it's on the 2K forums:
XCOM Commanders,
Thank you for your patience and dedication in helping the Enemy Unknown development team identify and fix the reported AI Teleport bug. We have released the Community QA build live, so all PC users will now benefit from your communal effort.
Unfortunately, a non-game breaking alien reveal bug has been exposed, as reported by the community. In the interest of erasing the AI teleport issue as quickly as possible, we are moving forward with pushing this build live. We would like to focus on this new soft reveal issue in a future patch, to be communicated at a later date. Thank you so much for your help, and we hope you continue those Iron Man runs now!
So, it's a quick patch that should have fixed the teleport bug. If not, there'll be another patch coming soon-ish. They could have spread the word on that a bit better.
