Hmm… I’ve been playing around with the MinAgentHalfHeightPct, and it’s still not working properly for some reason. It seems I may have to work from UE4 source and debug into the HasReached function, eh? 
EDIT: Now I’m just confused for all sorts of reasons. Now I’m noticing the collision capsule is getting stuck on corners with, as far as I know, correct nav mesh/system settings for my character. The red line in the image below is just a cast from the actor’s position to the current move destination (since segment checks are done with the actor’s feet, this debug visual is wrong, but it gets the point across).
