Has there been a Glitch?

Currently playing as Maya at Level 75. During last nights game (Lynchwood) my system suffered a brief powercut. When I restarted the game I noted that my cash reserves had fallen from around $94million to $13.5million. Since noticing the difference I haven’t been killed (but come close a few times) and only bought sniper and pistol ammo. How can this happen?

I believe rat thiefs can spawn in lynchwood and steal your money
