lnd: `ChanStatusBorked`, closure with ZFR, "ghost" balance sent to unknown addresses

Background

Channel with ZFR that out of the blue closes, bos bot just reports “closing channel”, not a force closure. I saw no unconfirmed txns in my cold wallet, out of which I took an address to attach to the channel open I initiated. Onchain, I see this tx corresponding to the closure: cda9474e4cabc591b5a79503784b039d800729a19b07cd0ea982acde22c182ce The output addresses are not known to me. This is the relevant output from lncli pendingchannels

From the records saved by lndg about the channel, local I had 585497 + 1734 commit, which summed to the 1512769 lndg had saved as remove balance is exactly 2100000.

Grepping ERR from logs I see

[ERR] LNWL: ChannelPoint(58839114c2a2d8011126547f03f2ea6395242bef8498353c21c1bd36ec53f69b:0): sync failed: remote's next commit height is 37795, while we believe it is 37793!

I know at this point this must have been a FC which my lnd didn’t detect as such, will I recover the funds automatically via sweep or do I need to do anything special?

Your environment

• version of lnd 0.14.3
• which operating system (uname -a on *Nix) raspberry bullseye
• version of btcd, bitcoind, or other backend 0.22
• any other relevant environment details

Steps to reproduce

Nothing special

Expected behaviour

Don’t even know what to expect

Actual behaviour

Closure, funds disappeared
