why is my ship accelerating for no reason, all of my engines are off

[StarKerbol]

i made sure all of my engines are throttled off (i realized i put in the wrong category)

Welcome to the forum @StarKerbol, your issue has been moved from KSP 1 Discussion to KSP 1 Gameplay questions.

An image of your vessel would help, does it have RCS?

[StarKerbol]

No it doesnt @James Kerman it doesnt have any rcs

Are you using any mods?

[StarKerbol]

i used mods but none of them are related to my spacecraft (except ReStock), its just a basic spacecraft

Does your vessel have any clipped parts? This can sometimes create accidental kraken drives.

[StarKerbol]

oh yeah i do, the engine is clipped because it looks janky when its in the original position but that clipped engine kraken encounter never happened to my other spacecrafts taht had a clipped engines

Try modifying it in the VAB and see what happens. I'd keep the original and save as a new version as kraken drives can be useful.

Okay

there was another guy a few months ago who had the same problem, it turned out it was just a bug. you tried reloading? restarting the game?

@StarKerbol Did you find a fix or workaround for your problem?

I see that others already mentioned clipped parts. EVA Construction, attaching parts to an existing ship, can also trigger mysterious acceleration. Clipping and EVA Construction are usually safe but when they go wrong they can go very wrong.

Another acceleration-like problem I've seen might be due to KSP math rounding errors. These drifts are usually small but sometimes a trajectory that was going to enter a planet's SOI changes without warning, turning an intercept into a miss. The game setting include orbital drift compensation but that doesn't always prevent the problem.
