Bugs

This page lists errors, unintended behavior, and glitches found in PD2. Some major vanilla bugs are also listed.

Non-Vanilla
Bugs introduced in PD2 due to new features

General Bugs:
 * Flawless gems can only be promoted to perfect gems while in their stacked form.
 * Cubing three T1 maps with a Cartographer's Orb sometimes creates a white axe instead of a T2 map
 * In some situations having two items of the same type within the cube during a recipe can consume one of the items
 * Dual-wielding attack speed breakpoints are now always based on the faster weapon - this fixes Barbarian attacks, but Assassins have several melee skills which are technically dual-wielding but only the mainhand weapon is used. This results in a new WSM bug where a faster weapon can be equipped in the offhand to bypass the speed of the attacking weapon.
 * Some items in the Immortal King set have their set bonuses displayed in blue (like normal attributes) rather than in green.

BH-Related Bugs:
 * Attribute ranges on tooltips are sometimes incorrect
 * When multiple affixes (or other sources) add the same attribute, only a single affix's attribute range is shown rather than a combined range. Examples:
 * The 50% Damage to Undead automod for blunt weapons isn't included in the attribute's range.
 * Crafted items will display the standard attribute range (e.g. rolled affixes) without taking into account the attribute range from predetermined affixes.
 * When a runeword adds the same attribute as one of its runes, the attribute range doesn't include values from the rune. Example: Chains of Honor shows [35-45] all res in-game but is actually [50-60] since Um adds +15
 * List of attribute sources: prefixes, suffixes, automods, predetermined crafting affixes, corruptions, socketed gems/runes/jewels, superior affixes, pointmods
 * When an item has a "hybrid" affix with multiple attributes, each attribute range is still treated separately which can results in inaccurate/ambiguous comparisons. Example:
 * A Fine Small Charm adds +[1-3] damage & +[10-20] AR but the attribute range for AR shows [2-36] in-game since the Bronze/Iron/Steel affixes can add that much AR (but of course those affixes don't add any damage)
 * Magic items without a prefix/suffix will have an extra space in their name where the prefix/suffix name would be, making the overall name appear slightly off-center.
 * Some items have their default color built into %NAME%, so their color won't change unless their name is rewritten completely.
 * When changing zones via a portal, nearby items are updated before the MAPID gets updated so any items within a screen length of the portal will be displayed as if the character was still in the previous zone.

Note that attribute ranges and lootfilters are handled by PD2's open-source version of BH, which anyone may submit improvements for. The discord's #lootfilter channel may be a good place to learn more about it if you have questions, since devs and editors often frequent the channel and discuss BH-related changes there.

Singleplayer-Only Bugs
For all singleplayer differences, see: Singleplayer
 * PlugY: Having too many items in a stash page with many affixes (especially maps) can cause a crash if that page is the most recently visited stash page
 * PlugY: Having gold in the shared stash can cause issues, preventing oskills and other stats from working correctly
 * PlugY: The "toggle stash" button may be set to the wrong stash upon loading until interacting with the current stash - putting an item on a higher page (such as page 200) in whichever stash is loaded first seems to fix it in some cases
 * Andariel quest bug (vanilla bug - fixed in multiplayer)

Vanilla
Bugs found in vanilla and PD2


 * Multiple corpse bug - rejoining a game with more than one corpse will result in only the highest value corpse being carried over and items on all other corpses being lost
 * Corpse limit bug - only ~15 corpses can exist simultaneously, so if a player dies while wearing gear and at the corpse limit, the gear will be lost even without rejoining a game
 * Strength bug - gear not visible to other players; may also contribute to losing items when there are multiple corpses
 * Broken-offhand-whirlwind (BOW) bug - when dual-wielding and using whirlwind, if the offhand weapon is broken (0 durability) and has 1 gemmed socket (to prevent it from disappearing), the mainhand weapon is used as both the mainhand and offhand weapons
 * Failed-to-Join (FTJ) bug
 * Next-hit-always-misses (NHAM) bug

For a more complete list of vanilla bugs, see wikis dedicated to vanilla. The Amazon Basin wiki does an especially good job, with bugs typically written in red in their relevant categories. Another example is this list of 200+ bugs that focuses on what should be fixed for D2: Resurrected.
