Thanks.
This is a common bug, and it can’t be completely prevented, but frequent game restarts help.
We don’t have logs about it, so normally we can’t help without a video of the loss happening in the constructor. We have a guide on recording here: Recording your gameplay in Empyrion
The best we can offer you is to return it as a one-time exception 
Next time I notice you offline, I’ll put it into your inventory.
