Pumpjack looses all fuel when crashes occur

Sorry to hear you've lost lgf. I've had a quick look and these "hard crashes" are due to the current worldwide ddos attacks, your ping will go really high and it will seem to lag/rubberband, the server is still there and hasn't crashed. (If you can reconnect to the server within 1 minute is great tell that the server didn't go down/crash.) Things can get lost in these moments, these attacks happen less in offpeak hours and would be a safer bet to transfer lgf.
