an #htlc was worth 511 sats, but it cost 2_458 sats to redeem in a channel between 'ACINQ' and 'River Financial 1': https://mempool.space/tx/263d72d682d3d75abbd6d5c1873a0572bf9b4c55a7c082791f5126376e4eeb37/

someone lost their channel, their entire payment and had to send 1_947 sats more to the gods of lightning for the privilege, over 3x the actual value of the HTLC
