The last force close was peer offline (the peer was part of a lightningnetwork.plus liquidity triangle) and HTLC timeout. LND swept and burned 280k sat of  onchain funds trying to recover 50k from the channel. :-(

I’m feeling disillusioned by lightning in this high fee environment. It’s cost me many sats in forced channels closes, unconfirmed txs from third parties, I am unlikely to open new ones, and today, LND decided to drain my onchain funds (300k sat) to recover 50k sat. Uhhh L2 is no good if L1 is completely borked.
