Logspam and lag when calculating trajectory for an EVA Kerbal #181

Open fat-lobyte opened 3 years ago

fat-lobyte commented 3 years ago

Steps to reproduce:

  1. Launch Kerbals into the air with any method
  2. Perform an EVA
  3. Enable Trajectories

Observe the following logspam:

[LOG 14:52:50.130] CheckEncounter: both intercept UTs are infinite
[LOG 14:52:50.131] CheckEncounter: both intercept UTs are infinite
[LOG 14:52:50.132] dT is NaN! tA: NaN, E: NaN, M: NaN, T: NaN

KSP Version: 1.12.0 Trajectories Version: 2.4.0, current master

The oldest version that I have tested was KSP 1.8.1 and Trajectories 2.3.0 which also exhibit this bug.
