Engines fire but no thrust
Just wondering if anyone has had a similar issue. I built a ship to go out to Duna and back. Everything was fine until I reached Duna. after entering Duna's SOI my engines will no longer work properly. I can increase the thrust control and the engines produce noise and graphics as if they are working however the ship does not respond and will not move. The strange part is if I right click on the engine and play with the thrust control the engine information shows the thrust increasing and decreasing but again, the ship does not respond.

Engines:
1x - MRS Nuclear Quad engine, 2.5m, "Quad Nuke" - from modular rocket systems mod I think.
4x - LV-N "Nerve" Atomic rocket motor - From stock game

Some additional info, I am using the same stage on my rocket as I used to reach Duna, the engines worked fine to get there and nothing has changed on the ship. I have power and plenty of fuel. Other parts of the ship work fine, I can use all my experiments and rotate the ship. I tried restarting the game but that did not work. I tried shutting down and restarting each engine but that also did not work.

This happened to me once before around Mun using a cryo engine from a mod. I was able to use a different stage to get back to Kerbin and I figured that was due to an outdated mod, which I updated and it seemed ok after that; but since it happened again with different engines I think this must be a bigger glitch.

Any help would be appreciated.

Nope, it's just mods being mods. Most of them use cloned configs from SQUADs engines and this often backfires horribly. Redownload the mod and hope for the best. (alternatively replace the part cfg)

This can happen without mods too... its frustrating.

It happens in Vanilla so its not mods being mods,changing SOI in the current version can be like rolling a dice in an D&D game with a particularly vicious GM..anything can happen.

I can confirm this issue as well. Debug reveals that the OrbitDriver is having a fit and fails to bring the ship off the rails.

Since it's what has been changed in 1.1.3, blame the devs.

Fair enough, I stand corrected folks. Wonder how the hell I've escaped the wrath?

Glad to know it's not just me! Still sucks though...

Has anyone found a fix? I tried a few small things but nothing has worked. My crew is now hopelessly orbiting Kerbol in a broken ship. I don't really want to abandon the ship since it is carrying a lot of good data. I suppose I could mount a rescue mission for the crew and data but that sounds like a lot of work... sigh.

I've had the problem after coming out of time warp. Just once in a while though. I just F5 then F9 and it seems to fix it. Haven had a problem with 1.0.3 though...

You probably design differently to those of us that have tangled with this particular Kraken,each Kraken has different tastes.
I have a shortlist of design features for KSP that i know will attract various Kraken from over the versions and won`t do them ever again even if they are supposed to have been fixed.

Murinus...you might not like this suggestion but you can go into the save and alter your location by a couple of KM...that has fixed the problem for me a couple of times but it feels slightly wrong.

I might just do that.... I agree it would feel kind of wrong however I don't want to lose this mission and crew to a glitch in the game.

um.. if Im not mistaken Duna has an atmosphere and atomic rockets don't work in atmosphere yeah not a glitch

Not only is Duna's SOI way bigger than its atmosphere, but Duna's whiff of an atmo doesn't really cause the drop of thrust to kick in. People have taken off there with nukes.

Also, nukes don't flatly stop working in an atmosphere. They just produce a lot less thrust. Which would still be observable in space.

Well yes they don't completely stop but I didn't know if his ship passed the threshold where the drop in thrust made it so the rockets could no longer push the craft but thanks for pointing it out

Um, I had this happen once. Are landing gear being deployed? If anything clips through into the engine, it nulifies thrust.
