Virtual Characters Do Not Respond in Chat in Multi-Characters RPG (Aigne)

When trying the chat feature in the Multi-Characters RPG game on the Aigne platform, virtual characters do not respond to messages sent, with no indication that the system is processing or encountering an error. The steps to reproduce this bug are opening Aigne, running the game, entering the chat feature, and sending a message, but no reply appears. Virtual characters should respond according to the game scenario, but in reality, there is no reaction at all. To fix this issue, the development team can check server logs, ensure the AI integration or NPC script is functioning correctly, and test on various devices and browsers to determine if the problem can be replicated.
