Thanks for the issue report @lchao118.

Looks like this is related to a block reorg on testnet3. The block with the expectedHash 0000000000324c53985fbf64a8f9d1c7a2f7481e65d6d323e8a6f4b2b2eeb934 was orphaned, and replaced by the block with the block with the hash 00000000001b7b38f76696b02dcc5a3ef0a4c27668cea2c721a7e75a593054e4.
