- Vanilla M2 bone struct (108 bytes) with 28-byte animation tracks - Version-aware bone parsing (vanilla vs WotLK format detection) - Fix CharSections.dbc field layout for vanilla (variation/color at 4-5) - Remove broken CharSections.csv files (all fields marked as strings) - Expansion data reload on profile switch (DBC cache clear, layout reload) - Vanilla packet encryption (VanillaCrypt XOR-based header crypt) - Extended character preview geoset range (0-99) for vanilla models - DBC cache clear support in AssetManager
