So far the only "universal" problems i have seen are:
-Magical resistances borken.
-Dragons acting wierd.
-Graphical bugs.
- Broken mouse control
- Must click multiple times to click anything
- Mouse-over text does not work 80% of the time
- Mouse selects wrong text
- Scrolling is buggy
- Buttons stick between menu's
- NPC's comment on things you are not doing... (Careful with that fire, while I have my bow out.)
- Constant crashing to desktop
- Constant over-looping of sounds/conversations making it impossible to hear locked dialogue that does not repeat
- Delayed sounds, stacking infinately, playing all at once, once dialogue is finished. Again, making it impossible to hear "critical non-repeating dialogue."
- Broken missions
- Items not being removed
- Millions of arrows and dropped items not cleaning-up once dropped or left behind
- Creatures and players getting stuck on everything, including invisible things
- Items being invisible, but still selectable
- Animations failing, going fast-forward, or wrong times, or not at all
- Game "staples" not functioning. "Time between shouts 0%" does not reduce time between shouts to 0 seconds. Magic resistance, or specific resistances not working. Armor not actually resisting physical damage. ... endless list...
- New-cell loading seems to constantly crash the game, frozen screen, randomly.
- New sounds seem to crash the game, or create horrible static sounds.
- Shadows are horribly rendered on almost all cards, banding lines all over, unshadowed edges of players and items...
- Fog and lighting seems to kill framerates and game speed, where it should not.
- Lights fail to load randomly, yet still cast shadows.
- Textures get "stuck", or flicker, or pop-in/out when they should not. (Wrong LOD's and LOD's not being obeyed.)
- Water-mapping is tied to a game-setting, which, if not selected, causes water issues with most effects. (Those who have that option selected, do not see the issue. Those with it off, by the games settings for that card, have nasty water in rain, or while entering the water.)
- AutoSave on "Fast-travel" and "Exiting doors" and "Auto-interval" crashes the game a lot, and behaves in undesired ways, over-writing manual saves and other players auto-saves, and no options for number of saves, leaves 4 that re-write over one another. Making auto-save almost useless, unless it is used only for crash-recovery... Ironically, caused by auto-saving.
I could go on, all day...
