While attempting to catch vampirism on one of my characters I noticed a rather game-breaking bug. Any sort of buff that would normally wear off after a certain number of hours refuses to do so. This includes shrine buffs and resting bonuses. When I go to a shrine and receive the blessing, it will remain indefinitely, even after waiting for longer than the duration.

This bug also affects Sanguinare Vampiris. After the disease is caught it will never progress to full vampirism. In addition, if the player is made into a vampire through console commands the current stage of vampirism will not advance.

This bug persists even when all mods are removed, including on new games started with no mods running. Also, I run the game with a timescale of 8, although the new game I tested it on had the default timescale of 20 and it still persisted.

If anyone has encountered this bug or has an idea of what game setting controls the passing of time affecting spells effects, please let me know.

Here is my mod list:
