4.3.92 Proc grid mover bug?

General Grid graph
#1

Hello again,

I recently updated to 4.3.92 and have been getting these errors:

IndexOutOfRangeException: Index was outside the bounds of the array.
  at Pathfinding.GridNode.GetConnections[T] (Pathfinding.GraphNode+GetConnectionsWithData`1[T] action, T& data, System.Int32 connectionFilter) [0x00000] in <00000000000000000000000000000000>:0

Thats the error i get in builds (Pc, webgl, android, etc.).

In editor i get these errors spamming:

It always eventually occurs when i move far enough away, but its not consistent when it occurs, for example i can move enough away from the starting position for the mover to update 1-3 times. But it eventually throws this error and then i cannot move anymore. Or sometimes i can continue moving, but it spams the 2nd NRE log

I wonder if this is in anyway related to my issue. I’m using the Procedural Graph Mover in the Beta and get similar errors once I start moving around. I’m using a Recast Graph though.

Hi

Thanks! I have managed to replicate this, and a fix will be included in the next beta.
