Auto-trade doesn't seem to work? I had manual trades active then those timers ran out. But I had auto-trade active before they expired. It's been auto-deducting it all the whole time so these trades cannot be inactive.
I think Auto-Trade tried to just deduct the whole cost of the contract over again when it expired. But if it's going to do that, then what is the point of the per-second auto-deduction?
*edit* Can confirm that Auto-Trade is double-dipping and will fail if you don't have the resources in reserve. It's better to just buy up front.
