Not really a typo, but on a re-read I noticed in my eBook version:
Item 1: Chapter 144
Stormblessed, collapsed, his hand smoldering, several fingers missing.
Kaladin thrust out his broken hand - withered, with only the thumb and two fingers remaining - as he reached the ring of weapons.
I thought Kaladin should be missing at least 3 fingers based on the usage of "several".
