hi, I bought credit back in Fe

hi, I bought credit back in February, but for some reason when I just checked my account, it had a balance of 0.37 USD. I should have more, as I never re-purchased any game credits. why did it go down without my having purchased anything?

If you have used a node as Pay-Per-Traffic, it would double consumed your credit as calculated network traffic based on the node.

Your computer <-> node <-> the game server

Then, actually, the credit calculation can be delayed around 30 minutes to 2 hours so you may belated notice that
