🐛 Bug Fixes

• Fix Calamity2 tile loading: support new dense .twld format #1075

• Add ParseTileDataDense/ParseWallDataDense for new tileData/wallData format

• Add BuildTileDataDense/BuildWallDataDense for round-trip save

• Fix 1-based saveType indexing (0=vanilla, 1+=mod tile map index)

• Add bounds checking for stream desync resilience

• Fix legacy format to read initial skip bytes before first record

• Add 4 Calamity2 real-world tests (parse, quadrants, round-trip)

• Add RawTileData/RawWallData properties to TwldData

• Fix mod tile/wall rendering: accurate colors, layer depth, Safe prefix #1075

• Sample tile/wall colors from first texture frame instead of full-sheet average

• Add SampleFirstFrameColor() to TmodTextureExtractor for rawimg textures

• Fix tile fallback colored square rendering at LayerTileTextures depth

• Add Safe* prefix wall matching (mirrors existing Unsafe* fix)

• Log unmatched wall names at debug level for diagnostics

• Fix pre-existing unit test failures

• Add SaveTypeToTileMapIndex/SaveTypeToWallMapIndex lookup population in TwldFileTests

• Fix ModTileEntry_FromTag expected SaveType (index+1 when no "value" key)

• Fix WallProperty.Id serialization: add JsonIgnoreCondition.Never to prevent
  WhenWritingDefault from skipping Id=0 (which deserializes to default -1)

• Add textureWrap data for tile 185 (Small Decos) in tiles.json

📦 Other Changes

• TModLoader .twld support: NBT parser, tile/wall overlay, round-trip save #1075

• Add BigEndianReader/Writer for tModLoader's big-endian NBT format (TEdit.Common/IO)

• Add TagCompound and TagIO: GZip-compressed NBT serializer compatible with tModLoader

• Add TModLoader/ module: TwldFile, TwldData, ModTileEntry, ModWallEntry, ModTileData, ModWallData

• Parse .twld sidecar: header, tile/wall maps, binary tile/wall data, chest items, NPCs, tile entities

• Overlay mod tiles/walls onto World.Tiles using virtual IDs beyond vanilla range

• Register dynamic TileProperty/WallProperty with stable hash-based placeholder colors

• Strip mod data before vanilla .wld save, re-apply after (transparent round-trip)

• Preserve unmodified .twld sections (modData, bestiary, killCounts, etc.) for lossless save

• 25 new tests: TagCompound round-trip, BigEndian encoding, binary tile parsing, entry serialization

• ModScraper: extract tile/wall colors from .tmod archives #1075

• Add TEdit.ModScraper console app to scan .tmod files for tile/wall textures

• Support both PNG and tModLoader .rawimg texture formats

• Sample weighted average colors from non-transparent pixels

• Output modColors.json mapping mod:tile → hex color

• Search Steam Workshop and tModLoader Mods directories by default

• Add modColors.json loading to TwldFile for better mod tile rendering

• Fall back to hash-based colors when no scraped color available

• Cache mod colors after first load for performance

• Add 8 regression tests: vanilla world guards, modColors.json parsing

• All 21 TwldFile tests pass, 0 regressions

• World Explorer: add Vanilla/tModLoader toggle button #1075

• Add toggle button in search bar to switch between Vanilla and tModLoader worlds

• Filter world list by IsTModLoader flag from world header

• Scan tModLoader worlds folder (My Games/Terraria/tModLoader/Worlds)

• Show world count for each mode in the toggle button

• Auto-select tModLoader mode when no vanilla worlds exist

• Add localization keys: world_explorer_tab_vanilla, world_explorer_tab_tmodloader

• Load mod tile/wall textures from .tmod archives at world load #1075

• Add TmodTextureExtractor to read .tmod archives and extract tile/wall textures (PNG + rawimg)

• Add name-to-virtual-ID mapping in TwldFile for bridging texture paths to tile/wall IDs

• Wire LoadModTextures into WorldViewModel load pipeline after RegisterModSprites

• Add Texture2D loading helpers for PNG bytes and raw RGBA with color key transparency

• Process texture queue in render loop for deferred mod texture creation

• Fix rawimg decoder to handle version=1 header prefix (3 int32s not 2)

• Find .tmod files via cascading search: tModLoader Mods folder, Steam workshop

• Add 19 unit tests for rawimg decoding, name mapping, and real .tmod integration

• Add tmodloader-support.md tracking remaining mod support work

• Item editing

• Mod chest item editing: copy/paste, UI display, item textures #1075

• Copy/paste now carries mod fields (ModName, ModItemName, prefix, NBT data)

• NetId setter clears mod identity so vanilla item selection works cleanly

• Chest editor shows italic mod item name when IsModItem is true

• Extract item textures from .tmod archives, display 24x24 previews

• FastChestItem template uses MultiBinding for mod+vanilla preview lookup

• Add ModItemPreviewCache (string-keyed) and ItemPreviewMultiConverter

• Fix pre-existing: UndoManager TileImportance bounds check for mod tiles

• Fix pre-existing: ClipboardView binding path (Buffer.Name)

• Mod item support for tile entity editors #1075

• Add mod fields (ModName, ModItemName, etc.) to TileEntityItem and TileEntity

• TileEntity.ToItem()/FromItem() helpers for single-item entities

• TileEntityItem carries mod identity through Copy, ToItem, and implicit operators

• Item.ToTileEntityItem() and implicit operator preserve mod fields

• ApplyModTileEntityItems: overlay .twld NBT mod data onto tile entities at load

• RebuildModTileEntityItems: serialize mod data back to NBT at save

• Fix sync save path missing RebuildModChestItems call

• Copy/paste now works for all single-item entity types with mod identity

• XAML bindings for IsModItem/ModItemDisplayName on all tile entity editors

• Updated tmodloader-support.md with tile entity architecture notes

• Convert console.wld to LFS pointer
