I got on the game yesterday after not playing the game for over a year. And I find 2 things. First at the end of the bridge heading into Ivarstead from the south. There are 2 semi round sections of wall that was never there before. And secondly in riften there is a guy at the blackbriar medary that is used to level up speachcraft over and over again. but this time it stop starts and glitches and can only be done once. what happened to my skyrim game???

The speechcraft loop with that NPC was fixed a long time ago. (in the last patch I think)
