Yeah we didn't expect this many people to actually place a bet, and we also didn't expect all the errors to pop up with sending payouts. Liquidity issues, limits on receiving, pending HTLCs, routes not available, etc. Lightning still has a long way to go because we simply can't repay people if reliability is not guaranteed. When we get the error "invalid lightning address" then it's kind of tough to send a payout to that person.

If you have a pending payout let me know and we can sort it out manually.
