no, we did not force close any channel manually. this must have some other reason. but it has been generally observed with some LND nodes I think.

Looked into it and there was a close issued from your end.
Just the vagaries of Lightning.
My node also force closed with Muun's node because they became unresponsive.
Unconnected but simultaneously I have 13m sats on chain but that I can't touch. Will have to ask Lightning Labs on Slack for help with that.
