Ark: a double-tapped zap no longer spends one coin twice

2026-10-04T15:58:34Z

A reconcile pass that began before the first zap took its coin handed it back as spendable (the server still said so) while the zap was in flight; the second zap picked it and the server refused: 'vtxo … already spent'. Coins whose state changed during the pass are left alone. And a payment refused for an already-spent coin now reconciles and pays once more instead of failing with the raw error.
