heya! if chatgpt responses stopped working after a while it tends to be openai blocking it because you don't have enough credit or a payment method setup there
i will reccomend then to come over to our discord server and we can troubleshoot it together~ if you can talk to the pet through the pet personality window but its not reacting to events then probably there's some other misconfiguration or error happening. We can check it together more easily over there. Link to our discord is in the itchio page ♥
