It’s a game bug and not your fault. Nothing you can do but hope it doesn’t happen again.
If you can find a way to reproduce it at will then the developers can fix it. Until someone finds a way to replicate it and force it to happen, the devs aren’t likely to find the cause and fix it.
Maybe it has to do with the cb:getshiphere command, i’m shure that the last 2 times the deletion happened to that hv, i had used that command some hours before. after the command, i docked and didn’t use the hv until deletion. maybe it’s a hint.
Often its connected to changing playfields and docking vessles. Sadly as TwitchyJ mentioned there is no repro case
We gave the devs tons of information the last month to check it again, but I fear we are no further then before.
