-Enemy weapons and armour not despawning.
-The bug that prevents the civil war from progressing, forcing me to do the main quest path to solve it.
-The bug that during combat shouts sometimes do not activate properly.
-All the bugs associated with things respawning/ resetting when they should not, such as the Forsworn at Kolskeggr mine, the named giant spider, the draugr in that sinkhole mine, and the entrances to Blackreach from the Dwemer ruins, which in one case prevents access to Blackreach from the point it resets.
