I had a force closed on a channel opened by me to a peer which I know and we talk about it at the time. We tried to figured out who did trigger the force close as any did it manualy, one of the node might have done it automaticaélly somehow. The peer node did have other force close at the time that all happened in a short period while I had only this one, we conclude that it was initiated by my peer node somehow. However the fee for the force close was taken on my side and it was during extreme high fee environnement and the fee was even significant higher than the network need for passing in the next block. It was like 200ksats or more, I don't remember exactly.

I never used any circuit breaker or automation but haven't much other issues so far beside a stuck force close, on purpose by me, that got stuck (and still is) due to 12ksat/vB fee and non-anchor channel type. I hope to solve it eventually with help from the other peer or by paying a transaction accelerstor like ViaBTC or Binance are offering.
