Time Warp Bug

[Wizard Kerbal]

     On Xbox one, Radial preset.
     I’m attempting my first interplanetary mission to duna, so I stretched my apoapsis to kerbin’s SOI edge, then plotted a 150 m/s burn to intercept Duna. When I engaged time warp, The burn suddenly became 2,768 m/s. I reloaded a quick save, replotted the burn, then when I engaged time-warp the burn became ~1,980 m/s. How do I avoid this?

And please don’t say don’t use time warp, the burn is in 38 days.

I don’t think this is a bug really. I think that it’s Kerbal Space Program recalculating the muni ever to make sure it’s correct. For me cometuimes it does that too. It all depends on where you are and the situation. I think. (I’m PS4 player)

I’d believe you is it wasn’t for two things:

1. Nothing changed about my spacecraft, except location in my orbit.

2. This has never happened to me before

It's a glitch specifically with auto time warp, and it only happens on first activation. Something about those first few frames of accelerating to a high time warp speed causes the glitch. Note that it's not the manuever itself changing, but the position and heading of your vessel, which can be proven by monitoring things like apoapsis and periapsis before and after engaging auto time warp. The manuever only changes because it was repositioned, although you may be able to fix the manuever by adjusting it again by any amount.

You'll find this problem goes away if you manually enter time warp instead. Go at least to 5x time warp. Then it doesn't matter if you manually warp forward or auto time warp ahead from there. You may still see a tiny jump in the orbit of your vessel, but it will be much less than with auto time warp.
