Vibration and Explosion caused by UNKNOWN CAUSE

@AndrewGarrison I forgot to save TwT
But I have a similar sandbox, a space station in orbit with basically the same structure. That time I used SpaceShuttle CheetahStar to dock with the shuttle's dedicated docking port on the NISS, and there was a vibration and an explosion. That docking port is similar in structure to the shuttle's dedicated docking port on the ISS.
Here is a link to a similar sandbox

Do you have any sandboxes saved prior to docking so we can reproduce the vibration and explosion?
