Sorry for the screenshot, I can't move the camera.
I'm trying to dock 2 tanks together using 6 docking ports on each one. Not all the docking ports work at the same time and whe the ones that work get close to 100% the craft disapears and the camera gets stuck.
Side note: You can't dock a craft with itself, you have to first detach the bottom tank from it's docking ports
Dev Notes: Here's a craft that demonstrates the issue most of the time.
