I took 3rd place in the Quant League: Alpha Competition for week's 11, 12, and 13.

In the Algorithm Lab backend, there's a button to "Withdraw" -- clicking this after week 11 to claim the $50.00 prize reduced my balance to $0.00, showing "Balance Withdrawal: -$50.00" but without asking me where to send these funds. After winning week 12, then Withdraw button claimed the minimum amount needed to withdraw funds was $100. After winning again, I'm now reluctant to try it again, as the first $50.00 disappeared.

I emailed QuantConnect via the Contact form a couple times without a reply, and reached out on Twitter without a reply. How does one collect their winnings on this site (which should now be $150.00 for my account) ?
