I never had the problem of not being able to interact with the Alchemy Mutagen Table in Corvo Bianco prior to 1.22, but since updating to the latest patch, I can no longer access it. All i can do is ignite/extinguish the candle on the table.

According to the patch notes, this issue was fixed. But it looks like it has inadvertently started causing the bug for me. Anyone else encountering this? I have finished the main story and most of the side quests.
