[CLIENT] Conquerer "damage that would have been mitigated" showing a NAN result

A few details on this game: it was one for all with Illaois, I had the runes listed in the photo, was about a 30 min game.

Afterwards I checked and my conquerer "true damage that would have been mitigated" read @f3@ as shown above.

All of the other runes are displaying correctly, and this is the first time I've noticed it, so I wouldn't know how to get it to show back up.
