Added two new gotchas to the modding reference: - Modifier icons must use common/modifier_icons/ indirection (bare names, not full DDS paths) to avoid doubled-path resolution - on_game_start events must use scope=none with every_living_character for character initialization Also added modifier_icons directory to the directory layout tree and two rows to the Common Pitfalls table.
