I've just finished the main quests in Novigrad and am doing many of the side quests now. At the moment I am doing the Dandelion sidequest. I've started to experience frequent loading screens of about 10-15 secs. Where as until now everything was pretty much seamless (unless I died and reloaded of course). Can you guys please tell me what could be the issue? Is this a bug? Is there anyway I can reverse this?

Thanks.
