Oblivion:Unresolved Minor Issues

Several issues not addressed by the Official or Unofficial Patches still persist in Oblivion. Such issues are not significant enough to be considered glitches; that is, these issues do not affect playability and are unlikely to be noticed by the majority of players. But they are noteworthy in that many of them mirror issues that are fixed by the Unofficial Patches, or are clear cases where Bethesda Softworks made mistakes.

For a similar list of minor issues in the Shivering Isles, look here.

Weapon Issues
Missing Weapons
Battle Axe of Fracturing. In every weapon set Dwarven and better, the four Blade weapons have generic Disintegrate Weapon versions, and the four Blunt weapons have generic Disintegrate Armor versions. The only exception is the Glass set, which is missing this weapon.
Arrow of Hexing. This is the only ammunition found in the Construction Set that does not exist in-game.
Generic magic weapons missing from NPC weapon lists. These weapons are missing from the LL1NPCStaff2Greater100 used in NPC inventories: Greater Staff of the Weary (missing from list entirely), Greater Staff of Corrosion (missing from level 17 of the list only).

Weapon Erroneous Additions
Soul Trap Weapons on NPC weapon lists. The NPC Battle Axe weapon lists include Soul Trap weapons, while the NPC War Axe weapon lists do not. Soul Trap enchantments provide no benefit to NPCs (NPCs will not recharge their weapons even if they are carrying Soul Gems), so these Battle Axes likely are erroneous additions.

Permanent Bound Weapon Crash
When using a Bound Weapon that has been made permanent, if you have two of the same bound weapon, equipping one and dropping it will occasionally crash the game.

Attribute Issues
Names
Claymore of Jinxing. The Unofficial Oblivion Patch renames this weapon to Claymore of Curses. This is likely a mistake.

Types
Mace of Doom. This weapon, which is not normally found in game, is incorrectly characterized as a Bladed weapon.

Damage
Rusty Iron Bow, Rusty Iron War Axe. Most Rusty Iron weapons have 70-75% the damage of their regular Iron counterparts. The exceptions are these weapons, which have 100% and 63% respectively (8/8 and 5/8) the damage of their regular Iron counterparts.
Rusty Iron Dagger (CGIronDagger used in the Tutorial Dungeon). This version has the same damage (5 points) as a regular Iron Dagger.
Arrow of Discord. This is the only arrow in Oblivion with an area effect that does not have a -5 modifier to damage.

Health
Rusty Iron Bow, Rusty Iron Shortsword. Most Rusty Iron weapons have half the health of their regular Iron counterparts. These two weapons are the exceptions--they have 80% and 57% the health of their regular Iron counterparts (90/112 and 56/98) respectively.
Rusty Iron Dagger (CGIronDagger used in the Tutorial Dungeon). This version has significantly more health than most Rusty Iron Daggers (60 instead of 35).

Weights
Dwarven Arrow. Most standard ammunition weighs the same as its enchanted varieties. However, the Dwarven Arrow weighs 0.15 pounds, while all enchanted versions weigh 0.1 pounds. Since arrows of both lower and higher quality than the Dwarven Arrow also weigh 0.1 pounds, the standard arrow's weight likely is a mistake.
Silver Claymore, Claymore of Depletion, Claymore of Dispel, Claymore of Jinxing, Claymore of Sapping. The Silver Claymore and its enchanted counterparts weigh the same as the Dwarven Claymore (38 pounds). Meanwhile, the Steel Claymore weapons weigh a full 12 pounds less (26). It is likely the Silver Claymore weapons were meant to weigh 32 pounds instead.
Steel Battle Axe, Battle Axe of Diminishing, Quality Battle Axe Ember, Quality Battle Axe Soul Trap, Quality Battle Axe Spark. Typically, Battle Axes increase in weight by 7 pounds for each increase in material quality. The exception is the Steel set, which at 35 pounds weighs 8 pounds more than the Iron set and 6 pounds less than the Silver set. Interestingly, at 30.6 pounds the Fine Steel Battle Axe only has the correct weight if all Steel Battle Axes are reduced to 34 pounds.
Fine Steel Dagger. Virtually all Fine weapons weigh 90% of their regular counterparts. This weapon is the only exception (3.5 pounds instead of 3.6 pounds).

Gold Values
Rusty Iron Bow. Most Rusty Iron weapons are worth about one third the value of their regular Iron counterparts. This weapon is the exception - it is worth 91% (10/11) the value of its regular Iron counterpart.
Rusty Iron Dagger (CGIronDagger used in the Tutorial Dungeon). This version is worth more than the normal Rusty Iron Dagger (5 gold instead of 2).
Longsword of Depletion, Longsword of Dispel, Longsword of Frost (Martin's version), Longsword of Jinxing, Longsword of Sapping. Most generic magic weapons have the same base gold value as their unenchanted counterparts. However, these weapons only have a base value of 80 gold, while the Silver Longsword is worth 125 gold.
''Rugdumph's Sword. Most enchanted Silver Claymores have the same base gold value as their unenchanted counterparts. This weapon, however, has a base value of 125 gold instead of 130.

Magic Enchantments
Battle Axe of Jinxing, Claymore of Jinxing. The Unofficial Oblivion Patch erroneously assigns these weapons the same enchantments as ...of Curses class weapons.
War Axe of Enfeeblement. The Unofficial Oblivion Patch erroneously assigns this weapon the same enchantment as ...of Weakness class weapons.

Magic Charges
Claymore of Jinxing. The Unofficial Oblivion Patch assigns this weapon twice as many charges (1600) than most generic Silver magic weapons have (800).
Arrow of Cleansing, Arrow of Fire, Arrow of Hexing, Arrow of Immolation, Arrow of Jinxing, Arrow of the North Winds, Arrow of Savage Frost, Arrow of Silence, Arrow of Stillness, Arrow of Storm Strike, Stormcall Arrow''. These arrows have random enchantment values, and, because enchantments factor into a weapon's gold value, these arrows have gold values that frequently exceed higher quality arrows, or lag behind lower quality arrows.

Speed
 . Most Akaviri bladed weapons have a speed of 1 hit per second. At a speed of 0.9 hits per second, this is the only exception.
Reach
Most magic staves have a Reach of 0. This can cause game crashes, especially in heavily modified games.
