Hi,
Why is the autopilot broken?

Specifically on my models like bluebird (or ufo if you prefer), I 
started to implement a requested feature, but found it does not work 
like it used to.

The property:
/autopilot/settings/true-heading-deg

acts like it is being set by something else that shouldn't.
When pressing the Heading Hold button on the panel, my aircraft flies in
circles, because this property is constantly changing. Or with c172p
press [F11] to load autopilot settings, click True Heading, and attempt
to give it a heading to follow! I am surprised the c172p is broken as 
well, so it is not just my models.
Is there a reason the Autopilot on the top menubar is greyed out?

I narrowed down the time frame when this changed.
It works correctly Aug.11 and early Aug.12 (stays nil until set, and 
stays as set),
and is broken Aug.13

Changes include:
P source/src/Airports/simple.hxx
P source/src/Autopilot/route_mgr.cxx
P source/src/Cockpit/hud.cxx
P source/src/Environment/environment_ctrl.cxx
P source/src/FDM/JSBSim/**** 105 files updated by  ehofman (Is that you 
Eric?)
P source/src/Instrumentation/** 5 files

If you press [/] right after the scenery starts loading, then quickly
click down 2 directory levels, you can watch when this property starts
getting set. Throttle up and the autopilot heading starts changing
faster and faster, slows down at 180 from current heading, then speeds
up as fast as 10 degrees per second. Quite wild.

I also searched the last few months of messages, but can't find anything 
relevant to this.
