Dota 2 Items for Equipment

2.0.4 — Creative Tab Crash Fix and Upgrade Icon Redesign

Fixed

• Fixed the client crash when hovering or taking an active Upgrade Item from the creative inventory. LazyOptional.map rejected the intentionally absent hotkey tooltip result; the Curios lookup now resolves through a null-safe Optional.
• Replaced all 111 placeholder-style Upgrade Item textures with distinct 32×32 RGBA pixel-art sprites derived from audited Dota item identities and a shared Minecraft sprite treatment.
• Preserved every registry ID, category model, root bridge model, recipe, and gameplay configuration while replacing only the incorrect Upgrade visuals.

Added

• Added a reproducible generate_upgrade_textures.py pipeline for reference cleanup, chroma/background removal, pixel clustering, alpha composition, and PNG optimization.
• Expanded resource validation to require 32×32 RGBA Upgrade textures with valid alpha, non-empty content, and unique output hashes, preventing the old repeated-circle placeholders from returning.
• Added the crash report root cause and texture-regeneration details to release notes.
