I've seen various postings about this over time, but nothing as to how to prevent without using admin tools to copy / paste the grid. The problem is I don't always remember and have to load a backup if I notice a stray grid is gone in time.
Applies to space or ground encounters.
I am owner of all blocks listed in the control panel. Of course applies to the original PCU ownership.
Plenty of power - batteries on, Hydrogen engines on and plenty of hydrogen.
Cleanup is suspended
Any grid I take over is at risk if I get any real distance from it, but today I ran into a fun one. I was in my acquired ship at my ground base. I just took off straight up and just short of zero gravity the ship vanished and I was teleported back to the outside of my base. I was flying the dang thing with cleanup off and it just poofed.
I know I'll just have to reload a backup and copy / paste it but I'd like to stop the whole problem to begin with! Any suggestions?
