Stack Trace Error

[HeadClot]

Hey I am getting a stack trace error with bLandscapeTools.

Here are my system specs

OS - Windows 10 x64
Ram - 16 GB
Blender Version - 2.79 RC 1
GDAL version - gdal-201-1800-x64-core

What am I doing?

When ever I click the + to add a location it give me the following stack trace. I have defined a height map if you need it I can provide it as needed. I am using the Unreal Engine 4 engine preset.

bpy.context.area.type = 'VIEW_3D'
Traceback (most recent call last):
