19:05 <discord-> Z​eusbeer. — Fair explanation

22:39 <discord-> A​shnoom. — This seems fun

22:39 <discord-> A​shnoom. — > Check failed: I? <= I? (-nan(ind) m^2 kg vs. -nan(ind) m^2 kg)

22:43 <discord-> e​gg. — hmmm, can you get us a journal of that?

22:44 <discord-> A​shnoom. — the checkbox you need to enable before loading the save ?

22:44 <discord-> e​gg. — yes

22:44 <discord-> A​shnoom. — I don't know yet if it is reproducable

22:45 <discord-> e​gg. — I would think that https://github.com/mockingbirdnest/Principia/pull/2864 should have finally rid us of problems with those eigenvalues so maybe this is something being silly and giving garbage numbers, but who knows

22:45 <discord-> A​shnoom. — I was minimized while starting a KCTSim, so minimized while the game was loading VAB => FLIGHT. Mid-loading I clicked on KSP only for it not to do anything. So I a few moments later I clicked again and then it crashed with the above message.

22:46 <discord-> A​shnoom. — but, as mentioned, haven't reproduced, and don't know if what I did was of any influence on the reason of the crash 🙂

22:47 <discord-> A​shnoom. — the line before that metnioned that thing indeed:

22:47 <discord-> A​shnoom. — > E0407 00:38:12.402810 13132 symmetric_bilinear_form_body.hpp:218] Difficult diagonalization: {{-nan(ind) m^2 kg, -nan(ind) m^2 kg, -nan(ind) m^2 kg}, {-nan(ind) m^2 kg, -nan(ind) m^2 kg, -nan(ind) m^2 kg}, {-nan(ind) m^2 kg, -nan(ind) m^2 kg, -nan(ind) m^2 kg}}, stopping with: {{-nan(ind) m^2 kg, -nan(ind) m^2 kg, -nan(ind) m^2 kg}, {-nan(ind) m^2 kg, -nan(ind) m^2 kg, -nan(ind) m^2 kg}, {-nan(i

22:47 <discord-> A​shnoom. — lol

22:48 <discord-> e​gg. — that is going to be a difficult diagonalization indeed

22:48 <raptop> NaN eigenvalues? QM is even harder than I remembered

22:48 <discord-> e​gg. — well, send the logs; my guess is « something broke and fed us garbage numbers » at this point

22:49 <discord-> A​shnoom. — I will. Do you think the scenario I just described could indeed be of influence? That would aim me in some kind of direction as to how I could get something reproducable

22:49 <discord-> A​shnoom. — else I'll be shooting in the dark of what happened

22:50 <discord-> A​shnoom. — oohhhhhh, and I started in orbit

22:57 <discord-> A​shnoom. — I think I know the reason:

22:57 <discord-> A​shnoom. —

22:57 <discord-> A​shnoom. — I forgot to fill in the orbital height, so the field was empty. Assuming it is a floating point input it would default to NaN?

22:58 <discord-> e​gg. — I have no idea what you mean, I suppose you mean in KCT? If KCT doesn’t do validation to avoid NaNing your vessel that sounds like a bug, but wildly guessing at its behaviour seems dubious

22:59 <discord-> A​shnoom. — yeah, talking about KCTSim

22:59 <discord-> A​shnoom. — I'll talk with DRVeyl first 🙂

22:59 <discord-> e​gg. — then I have no idea, I have never touched that mod and I am not sure what it even does

23:00 <discord-> e​gg. — yeah, poking the good doctor Veyl sounds like a plan

23:05 <discord-> s​iimav. — If you leave the orbit altitude empty then it get defaulted to atmo+20km or SL+20km

23:06 <discord-> s​iimav. — If you leave the orbit altitude empty then it gets defaulted to atmo+20km or SL+20km (edited)

23:10 <discord-> D​RVeyl. — This'd be something for @siimav rather than me, I believe.

23:10 <discord-> A​shnoom. — perfect, #dev-feedback?
