OrbitDriver Warning!: xxx Debris had a NaN Orbit and was removed - what's this ?

[_Astra_]

Recently started experimenting with variable geometry wings by using the Infernal Robotics mod.

Soon got an exotic error and the game keeps crashing on supersonic or near supersonic speeds.

A short excerpt follows:

Never met a such condition before 1.1.2

Still unsure if it is related to mods or to the game itself.

yeah, i know what is division to zero. No, i know nothing on OrbitDriver or which debris exactly it is (the debug log is heavily spammed by NullReferenceErrors)

Surprisingly the game leaves no crash log, only a 14 Mb ksp.log

 

The IR is still 2.0.2 because 2.0.4 kills the game more often

 

Does anybody know what is the OrbitDriver and why a simple calculation gives a deadly error?
