The Oculite who broke his arm in Oculus has always healed back to full by himself on my past two playthroughs. Speaking to him will then result in him thanking me for helping him, which I didn't do.
I'm not 100% sure but I think there are other characters like this who are supposed to be wounded but end up being healed already. Not sure if this is an unintended side-effect of a change that was made to NPC's, seems to align with the NPC's now eating food patch maybe?
