Very tenacious wolf

A wolf was tracking me and I thought I was already in the clear, when I sprained an ankle. Before I could take a painkiller and keep on running, the wolf was on top of me. The weird thing was that I was at 95% health, maybe 10% tired and not cold or thirsty and I had a hunting knife, but I actually died from that attack. Usually I can chase a wolf off with just a few hits, taking 10-20% damage or even kill it, but this one just kept going and going until I was dead.

You can't always chase a wolf off. Sometimes they will kill you. Let us know if this happens often.
