$20.00 refunded twice on the same capture, 1s apart

Diagnosis

AI agent (anthropic/claude-haiku-5.5)

Two $20.00 refunds went out on the same $80.00 espresso order one second apart, with the same note ("Sorry about the crushed bag"). That looks like a double-click or retry, so the buyer has likely received $40.00 back when you may have meant $20.00. Nightshift cannot reverse a refund, so the $20.00 is at risk unless you confirm it was intended or ask the buyer to return it. The order is still unfulfilled, so please also decide whether it ships.

Whether the second $20.00 was a mistake or intended depends on a decision only the owner can make, and any follow-up with the buyer or the order is theirs to decide.

Note: Two $20.00 refunds were issued on order 1C746363Y3297422M one second apart (refunds 5GR00243LW545014S and 7JW01136N9777681R), so the buyer has received $40.00 of the $80.00 paid. Did you intend a $40.00 refund for the crushed bag? If not, should I ask the
