Can you tell me who was king of England in 1068?

ChatGPT knows all of the relevant dates, but can't seem to reason coherently about the sequence of events. It's unlikely that questions about 1068 specifically occur frequently in training data, so ChatGPT is left to rely on information from key dates like 1066, which it has a great deal of trouble extrapolating from. Further questioning (not shown due to screenshot limits) leads to it eventually getting the right answer.
