This is a known bug and I've prepared its fix. We'll be rolling out an update in the coming days. Till then, I'm refilling the accounts of everyone who lost their coins.
I've verified with our history logs and found that you lost around 2700 coins due to the bug. I've refilled your account with those coins and your new total is 2990 coins. Please login again to see those coins.
Thank you!
