Delirium fog disappearing way too fast

Bug Report ID: #392439299

Already had multiple maps where it was impossible to keep up with the fog, even though I completely ran past all monsters trying to stay in the fog(I have 25% movement speed boots), so the issue is not with my character being too slow.

I recently added They're coming to get you... (25% more likely to encounter unique bosses and killing rare monsters pauses the delirium mirror timer for 4 seconds) in my Atlas tree and the fog in my map is now disappearing incredibly fast. I feel like there is an issue with this atlas passive because if I remove it the fog goes back to lasting a normal amount of time. I'm not sure if this is related to the original post or if this is a separate issue.
