i have found a couple of strange bugs yesterday when i tried the game post patch..don't know if they were caused by it or were already there..
one is that multiple times,when walking on the bot in the ocean,i got teleported in the sky like 10 meters over the sea and then dropped for no apparent reason.
another was at a location on the coast of skellige..i believe the name of the location is something like "ruined inn",it's a village in ruin with a burned down house with some wraiths...well,the first time i went there it was completely deserted..then i went to novigrad,came back and now it was full of people...to be honest this probbaly has something to do with the fact that i have killed the wraths in the burned house..but i didn't get the usual "cutscene" after freeing a village from monsters...
last one,a minor one,was that at a nilfgaardian camp,the soldiers didn't spawn until i was basically in front of them...it was really strange,especially because there wasn't that many of them to load.
