Terrain data missing error

ArduCopter Copter 4.0
1

Hi Guys,
I’ve been getting Terrain data missing error from time to time even though that I’ve set the parameter Terrain Enabled to 0.
This error doesn’t seem to do anything, but I was wondering why it comes up?
I’m using the V4.0.0 stable version.

First of all please update to 4.0.3 as soon as possible.
