I have not played in a few months and have started playing again as I love this game. so a lot of downloading updates later and straight away my cut scenes the people have buttons on their chest??? Ok minor! then i start my side quest and the Pestilence bug hit me. I was unable to cure the town it only let me do half of it? So i checked online and found a thread saying complete Q&A’s quest first. So i did and managed to complete pestilence tho forfeiting other optional tasks along the line just to ensure not to bug out the quest. worked great! but roll up at my next quest Sport of Kings…and i cannot talk to Sir Divish to start the race?? there is no talk option. another bugged quest …i have decided to stop the game until it is playable. I hope one day it is.
What platform? If on PC do you have mods installed ? Such as easy lockpicking?
If your previous saves are from patch 1.4 you will have to restart the game. If not best of luck to you. 1.4 was known to corrupt saves and cannot be fixed with new patches. The only other option is to revert to an older save 1.34 or something like that.
