I started sending GUI Shop transactions to my Discord and I've seen some that show a negative balance after someone buys something:

Item Name
ammo.rifle
amount
50
Cost
125
Balance
-30.35

Any idea why this would show up like that? I thought maybe if the player didn't have enough, the Discord notification would look like that but I tested it on myself and it didn't happen. 

Economics supports negative balances, so check your economics settings.

Economics supports negative balances, so check your economics settings. 

Negative balances are disabled. So this is an Economics issue?

{
  "Allow negative balance for accounts": false,
  "Balance limit for accounts (0 to disable)": 0,
  "Negative balance limit for accounts (0 to disable)": 0,
  "Remove unused accounts": false,
  "Log transactions to file": false,
  "Starting account balance (0 or higher)": 0,
  "Wipe balances on new save file": false
}

So is this an economics issue?
