Your clone is built to only answer from context you've actually given it — it's designed to never invent progress, dates, commitments, or facts you haven't supplied. If it gave a wrong or made-up answer, it's almost always a gap in what it knows, not a random error.
What to do
Update your Knowledge Drive with the correct or missing information — see Managing your Knowledge Drive.
Check for stale data. If a project or role changed recently, your clone may still be working from the old version until you update it.
Tighten your guardrails if it's answering on topics it shouldn't be guessing about at all — see Setting guardrails and boundaries.
If it was asked something with no answer on file, it should have noted the question and offered to pass it to you rather than guessing. If that didn't happen, let support know — that's worth reporting.
