Been waitin for this to drop! Never updated to 1.2 but I took the plunge on 1.3 (spinnin the wheel of bugs to see what breaks).
My game now says 18.104.22.168 in the lower left corner of the system screen. The patch notes from Bethesda's Blog are:
Update 1.3 Notes (all platforms unless specified)
- General stability improvements
- Optimize performance for Core 2 Duo CPUs (PC)
- Fixed Radiant Story incorrectly filling certain roles
- Fixed magic resistances not calculating properly
- Fixed issue with placing books on bookshelves inside player purchased homes
- Fixed dragon animation issues with saving and loading
- Fixed Y-look input to scale correctly with framerate
Doesn't say anything about getting rid of dead Lydia stinkin up my house in Whiterun or crashing weddings.. But sure enough she's gone! And the flame atronach resisted my flame spells! Way to go Bethesda! Now (hopefully) they can enjoy the holidays...
