Prefix was required - In reality prefix is [ALL OS - Game Bug] I apologise in advance if this is a dupe report. I am sure a lot of people experienced an issue, when patched conics trajectory wobbles at warp x1. (in some cases predicted trajectory will wobble by hundreds of kilometres if multiple gravity assists are involved). I believe this is caused by the fact that the trajectory prediction is made by using the currently active probe/pod COM, rather than the entire craft's COM. Any rotation or vibration in the craft will add ~0.01 to 0.1m/s to the probe's COM and alter the predicted trajectory. The way to check is to get one of those "wobble" orbits and let your craft rotate freely in one direction (SAS off). You will notice that the wobble will repeat itself with the same frequency as the craft's rotation. The wobble will also immediately stop if you warp 5x. If you unwarp back to physics the wobble will be a lot lower or completely gone. (either FP errors or inherent wobble of clipped/large part craft, these errors cause significantly lower wobble and are not considered in this report). I am not sure if images would help here, I will try to create a twitch highlight showing the issue ASAP if required. Suggested fix is to calculate trajectory from the craft's COM rather than the control part's COM. xJ.
