Last War Bug Wiped Out My Oil Without Any Upgrades

I play Last War using the account named ravenqueen88 in the Kings alliance (ID 2019103479001400). This morning, my oil amount was around 1,700,000, but by noon, it suddenly dropped to about 814,000—even though I didn't upgrade any buildings, research any technology, or do anything else that would cost resources. Over the course of the day, my oil went up slightly from 814,000 to about 920,000 without any extra spending, but this is still a massive loss compared to the 1,700,000 I started with.

Losing this many resources for no reason has seriously ruined my enjoyment of the game, and I believe there has been an unfair deduction or a glitch on my account. I request that you thoroughly investigate the game logs, clearly explain the reason for this missing oil, and restore my resources to their original amount if this drop was unjustified.

I kindly ask that you resolve this issue as soon as possible and provide me with a clear response via an in-game message or email.
