'Discerning the Transmundane' quest not working [closed]

I did everything for the quest up until harvesting the blood: after I went and harvested the blood I went back to Septimus and now he won't give me any options about giving him the Essence Extractor back.
Any clues as to why this might have happened and how to fix it?


Solution 1:

This is a very buggy quest. The bugs are listed in detail here:

https://en.uesp.net/wiki/Skyrim:Discerning_the_Transmundane#Bugs

The Unofficial Patch will fix most of the bugs, including yours.

You may not have the "Harvest blood" option despite having the Essence Extractor in your inventory.

PC Only: This bug is fixed by version 2.0.1 of the Unofficial Skyrim Patch.

PC: Use the console command player.addperk 79af5.

However, this option is only available if you have the PC version.
