9. Escape from Ginkgo Valley Bug

[zealous000]

There is a bug in Mission 9 of Escape from Ginkgo Valley where the NPC cannot be found at the location, and clicking on it does not progress the quest.

Going to the character selection screen and returning makes it work normally; this might also occur in other missions.

Binary Analysis — Root Cause Identified

Status: Cannot fix via JSON — phasing/entity sync issue in C++

Root Cause

This is a phasing/entity synchronization issue. The NPC entity is not properly spawned or made visible to the player in the correct quest phase.

PHASING.json and TRIGGER_GROUPBASE.json are both loaded by the server, but the entity visibility/phasing logic in C++ does not correctly evaluate the player's quest state to determine which NPCs should be visible.

The character selection workaround works because the full login process reinitializes phasing state from scratch. This pattern (needing to relog to fix) matches other sync bugs (#93, #101), suggesting a systemic issue with the entity synchronization system in ContentsSync.cpp.

Fix Required

Debug the phasing/entity spawning logic to ensure quest NPCs become visible when the player reaches the correct quest step. The underlying sync system likely has a state tracking bug that affects multiple systems.
