Please help with checking validity of path to location

Basically I just want to confirm if AI is able to reach certain location. I’ve tried various methods like finding path synchronously etc but the results are very strange. When target location is in the posistion 1 on the screenshot the path is marked as valid but partial so I can get from this that it’s actually invalid because it’s partial. On the position two however even though there is no nav mesh at all the path is valid and not partial… AI thinks it can go there but stops before the null modifier. Is there really no simple, reliable way to check if location can be reached by AI? It seems like the distance from location to the nav mesh has to be very big for the find path function to return invalid path, maybe there is a way to influence this for example by changing some nav mesh settings? Does someone know if there is any place where those settings are really explained? Thank you in advance.

Here I’m printing the state of the same actor and as you can see it shows that the path is valid and not partial but projection to nav mesh returns false which just doesn’t make sense at all to me…
