NullPointerException thrown when I call moveAvatar

[cyli]

I get these errors every so often:

[OpenSpace] User NPC_1276816364083 [15] requested path from (0, 1, 0) to (6, 3, 0) on map 'map#1276816293734'
java.lang.NullPointerException
at com.smartfoxserver.openspace.commands.CalculatePathCommand.execute(CalculatePathCommand.java:79)
at com.smartfoxserver.openspace.OpenSpaceExtension.moveAvatar(OpenSpaceExtension.java:360)

It is not a PathfindingException - I was wondering if you knew what could be causing it? Is there a problem with the map, perhaps?

Thank you!

Also, I have observed that previously the same path was found correctly, and the map has not changed in the intermittent period.

Also no changes in the avatar type?
Can you send us an example showing the problem, so we can investigate it?

Was this problem ever solved ? I also have this problem occasionally, the avatar will get stuck and cannot move until map is changed.
