Probe engine not working

[king of nowhere]

the engine is fully throttled

the probe has full control

there is plenty of xenon and electricity

there are no malfunction indicators whatsoever

but the engine is not working.

to make matters even more strange, its sister probe, which is perfectly identical, works as it should

suspecting a bug i tried to reload the game, didn't work

what the hell???

I'm going for a hat trick here and saying.... Kerbalism?! It says Engine: ignitions 47%. Not sure what that means but 47 sounds low (compared to 100%). Is it something to.do with that like ignition coils have had it (not sure what kerbalism adds exactly)? What do the 3 buttons underneath it do?

no, it's 471. after the ignitions run out there is increased chances of malfunctions. but when the engine malfunctions, it turns yellow or red

the three buttons underneath are the usual one for set view, autostrut, toggle

Do you have fuel crossfeed disabled on a part somewhere between the tank and the engine?

On the bottom left it says 0m/s. Sometimes KSP gets the deltaV calculation wrong and misreports it, but........

between the tank and the engine i only have a small reaction wheel and a rovemate.

anyway, i did try deactivating crossfeed rules too

... but the engines still work.

 

well, since nobody can figure out an explanation, i think it's definitely a bug. thinking about it, i had a similar bug in my last mission too, where fuel would not be transfered between two adjacent tanks.

i scrapped the probe and sent a new one

[paul_c]

I think I've seen that bug too - where fuel should transfer, but doesn't. And its all going through (if at all) decouplers and docking ports with crossfeed enabled; and nothing like a heatshield to block it.

The only way I solved it was to revert the save to a previous backup - I am guessing the vessel was corrupted in the persistent.sfs file. Sending another would work around the same bug in another way though.

ETA just looking at the screenshot closely again - top left, the time is in yellow. This normally means its being timewarped (at 2x?) Controls won't work while timewarping...

never noticed different colors there. but anyway, i have the persistent burn mod for using ion engines, so controls do work with timewarp. and i could rotate the ship just fine, so no, it wasn't timewarped

That's not timewarp, the timer being yellow just indicates that ingame time is running slower than real time.
