Return from Moon broken

Opened this issue · 6 comments

KSP 12.3, MJ Dev #1343

Module "Return from Moon" - here: Mun - creates a node with 480 m/s, instead of the expected approx. 270 m/s.
Manually creating the node works fine, with the node having 269 m/s.

Also: Maneuver execution doesn't terminate properly, but, more often than not, tries to execute the last <0.1 m/s days later.

Forced RCS Ullage (see issue #1860) as well as broken Porkchop (see Issue #1874) are not present in MJ Dev #1343, hence I did revert to that version.

need logs

Nothing in the KSP.log when creating the node. What logs do you need?

Here are some screenshots for starters:

Regarding node execution termination:

Alas, even going back further until build 1225 (that was the version that fixed the asparagus staging bug, see issue #1658) doesn't help at all: either I get the 480 m/s, or MJ is unable to create a node at all. :(

Another note: since build #1227 the fairing staging has gone bad for me: I used to have the fairing in its own stage, to have it autostaged between an altitude of 65+km, and the circularization node. That's no longer possible, unfortunately.
Why has that change been made?

The ReturnFromMoon version in the latest dev produces a ton of logs in KSP.log, they're sufficient for me to replicate the problem entirely without even having to fire up KSP. I really need those.

The fairing algorithm changed to fix common issues, and may have deliberately broken less common issues:

And chatting about random other problems in issues isn't useful at all. This isn't "chat and complain to the devs about everything wrong" -- it needs to stay focused on a single bug. For chatting there's the RO discord (where other users may wind up answering your question, instead of taking up all my time)

Let's stick with Return from Moon then, here's the KSP.log: https://file.io/qy9rxfJoga0s
What I did: Start KSP, jumped to the vessel orbiting Mun, created the node. Switched back to the KSC, quit the game.

Nevermind...

Every new build resolves one issue and introduces two new ones. From Asparagus Staging errors, to oscillating rolls, to RCS errors, to functions like Return From a Moon, to Porkchop calculations. Not even talking about PVG, non-working attitude adjustments, maneuver node execution, and so on.

From my perspective: you simply don't care. Don't care if you break stuff (or not). You just enjoy your happy playground, regardless.

I can't stand your attitude any longer, Larmont, and you probably can't mine as well.

Feel free to close any tickets I might have created.

I'm out of here.
