I've recently bought an item on Openbazaar and after paying, I wanted to withdraw the rest BTCs to my wallet.
I couldn't do it from the Openbazaar's wallet because of "insufficient balance" so I thought I could sweep the rest to my mobile wallet.
So, I inserted the seed to Ian Coleman's web page (offline, downloaded from Github) to search for the private key of the change address (I know the address from the transaction).
The 1st address, of the list, was the one I bought the item.
I've browsed several hundred addresses (one buy one and using ctr-F) without finding the changes address (however the BTC is there, but where)...

Any ideas ??
