So i downloaded the extinction dlc first showed 15g got to 100% then was stuck at that. It then started downloading something else wouldn't say what it was but said it would take 1 hour so I waited , it got to 2 seconds remaining then jumped all the way up to more than a year!!!!! So i shut steam down started again. It started another download which was small then went to a 20g download , let it run over night, woke up saw another 29g download happened and showed that there was a corrupted file with extinction.
