Ship self destructs if game wasn't played for around a month

[Wincil]

If the game wasn't played for around a month, upon joining a message appears from crew that time's up for self destruct, even though no order for it was given.
First time this happened, I heard explosion upon loading in. My ship had around 10% hull health. Still had fuel, but no crew inside. Ended up falling on a house and staying here.
Second time this happened, ship was in the orbit. No response to system hail. Probably same thing happened, but without corrosion.

I had the same issue
