Just uploading my save file because it's a little more prepared than the temporary save file they give you to start the expansion.

Save contains;
lv 39 character
respec potion
all places of power discovered (unless they added more in the dlcs)
all superior oils and potions
olgierd's sword (from the Hearts of stone dlc)
viper armor set + both viper swords (from the Hearts of stone dlc)
mastercrafted cat armor set
mastercrafted wolven armor set
mastercrafted ursine armor set (schematics only)

Hearts of stone is completed, with Olgierd saved.
Main quest is completed up to the final confrontation with the wild hunt.Yen romanced. 
Ciri interactions completed (leading towards the witcher ending)

EDIT: i'm actually missing cursed and draconid superior oils, sorry. (draconid oil can be found behind a wall broken with ard in a small cave, i've included the pic, if i find the other oil i'll add the location to that too).
