Craft Jitters at high speed and low altitude
Only using Restock, Restock + and Principia, on a fresh sandbox save, x64 version 1.12.5.
When going really fast at low altitude (speed needed depends on altitude and plane design, using a simple rapier https://imgur.com/a/mZsxA8N it starts at around 800m/s bellow 2000m and 1000m/s at 5000m) the plane and camera shakes side to side, increasing in severity with higher speed until the ship gets separated and broken. The aircraft is still a bit controllable. Video: https://imgur.com/a/rKuZTdX (warning, sudden motion)
This also happens on reentry with a rocket.
Of course if i remove principia from GameData this stops happening.
Sorry for not replying earlier. If you can still reproduce the problem, could you give us a journal?
I hope the files work well. In the test i started the logging, entered a ship on the runway and launched it. Once it reaches a high velocity the bug starts and I cut throttle. Once the plane stops jittering and behaves normally i stop journaling.
