Physics Range (pack/unpack) and Render Range (load/unload) are incorrect in the physics.cfg for Flying under VesselRanges
GOG KSP 1.2.2
GOG KSP 1.6.1
In physics.cfg under VesselRanges are incorrect for Flying
load = 2250
unload = 22500
pack = 25000
unpack = 2000
Note that the order how I understand KSP is:
1. Object is loaded (rendered)
2. Object is unpacked (physics is applied)
3. Object is packed (physics is removed)
4. Object is Unloaded (rendered object is removed)
The objects physics is still in affect when its unloaded for Flying. I have no idea how this would affect the game.
Has been like this since 1.2.2 by the looks of it
Thanks goes to taniwha who showed me this.
