[Critical][Bug][4.2.5][Unity 2018.3.7f1] NullReference Pathfinding.TriangleMeshNode.GetVertices

General
1

A*PP <4.2.5 crashes with ReflectionException after upgrading from 2018.3.2f1 to Unity 2018.3.7f1.

Updating to 4.2.5 (Website Download) fixes the Reflection Exception but a new NullReference occurs and constantly spams the player log (we just received a 1.4GB unity log filled with this exception message from one of our testers)

NullReferenceException: Object reference not set to an instance of an object

Hi

How are you creating this graph? Any particular code you are using for it?
Are you sure this is the first exception in the log?
