Spent about 2 hours prompt engineering examples to refine my GPT outputs in clay, being sure to save after each test. Then randomly all the examples I input disappeared. Thought nothing of it so just repeated this process again of testing the prompt with different training data in the examples and once again all of it disappeared right when I engineered the perfect prompt and clicked run all. Massive waste of time.
