I’m very sorry to hear that. But sadly we cannot do anything here.
First of all we do not recover structures that where destroyed by enemies (if then its a very big exception and we would need to see some proof of an issue).
Second: In your case your core was already destroyed before you logged out. Therefore it was already to late.
well thats sad 1 month of farming toveras down the drain. i have proof of the power outage at the time lol i guess i just quit playing and suporting the server with my accounts thanks anyway.
