Dvergr Pieces Patch

Dvergr Pieces Patch

Makes Tequila's Dvergr Pieces

work on Valheim 1.0.

This package contains none of Tequila's files. It installs his mod as a dependency —

your mod manager will fetch it alongside this one — and repairs it in memory when the game

loads. His assembly is never modified, never patched on disk, and never redistributed.

Everything you actually build comes from his mod. This is one 12 KB plugin that makes it

run again.

What was broken

• The build menu threw on every refresh

Valheim 1.0 refactored PieceTable. The field m_availablePieces changed from

List> (pieces grouped by category) to HashSet (a flat set), and the

old per-category list was renamed to m_availablePiecesByCategory.

The PieceManager bundled inside Dvergr Pieces still reads m_availablePieces as

List>. Because the name still exists with a different type, this is not a

load failure — its patches throw MissingFieldException the moment they run, the mod's

category never gets its slot, and Hud.UpdateBuild then throws

ArgumentOutOfRangeException on every frame the build menu is open. Over a thousand

exceptions in a few minutes of play.

This patch removes those two broken patches from PieceTable.UpdateAvailable and installs

equivalents that use the renamed field. Nothing else of PieceManager's is touched.

• The pieces were missing from the new build menu

Valheim 1.0 replaced the old category tab bar with a tag-driven menu (ByUsagePieceList)

that filters on a new field, Piece.m_usage. Prefabs authored before 1.0 have no usage

tags, so they matched no category and only ever showed under "Show All".

The pieces are now tagged so they appear where you would expect them. m_usage is a flags

field, so a piece can sit in more than one category — the chests and the shelf are both

Storage and Furniture, and the pole and beams are both Building and Architecture.

| Menu category | Pieces | Count |

|---|---|---|

| Furniture | bed, table, chair, stool, both chests, shelf | 7 |

| Stairs | metal spiral (left + right), marble spiral (left + right), wooden stairs | 5 |

| Building | black marble block, wooden pole, wooden beam, wooden beam 2x1 | 4 |

| Lighting | black core torch, placeable lantern, wisp torch | 3 |

| Storage | both chests, shelf | 3 |

| Architecture | wooden pole, wooden beam, wooden beam 2x1 | 3 |

| Walls | both dvergr walls | 2 |

| Decor | marble head, vines | 2 |

| Flooring | wooden floor | 1 |

| Doors and Windows | dvergr door | 1 |

| Crafting | fermenter | 1 |

That is 26 prefabs, covering all 24 pieces the mod advertises — the two spiral staircases

each ship as a separate left and right prefab.

All of them also appear together under a "Dvergr" category, the way the original mod

had them before 1.0. Because m_usage is a flags field, that is an extra bit rather than a

move: the bed is under Furniture and under Dvergr. It can be turned off — see

Configuration.

ByUsagePieceList builds its tag list into two instance arrays at construction, and the

rest of the menu reads only those, so the category is added by appending one entry to each

— no change to the enum and nothing patched in the BCL. The bit is picked from what the

array actually holds rather than hardcoded, so a category added by another mod (Jötunn can

do this since 2.30.1) will not collide with it.

• The fermenter did not accept newer meads

A bug Tequila acknowledged in his 2.9.0 changelog and never got to. The Dvergr fermenter's

brew list was baked into its asset bundle in 2024, so it refused everything added

afterwards — seven meads in total, from Ashlands and Bog Witch.

Rather than hardcoding a list that would rot on the next update, the fermenter now copies

any missing conversions from the vanilla fermenter at load time, so future meads work

automatically. Its 30% faster fermentation is unchanged.

Installing

Install it with a mod manager and Dvergr Pieces comes with it. If you are installing by

hand, you need both: Tequila's Dvergr Pieces 2.9.0 and this plugin, in

BepInEx/plugins.
