The following (non-exhaustive) list of things can lead to data corruption: [...] Aborting channel operation commands (see next chapter). [...]

Next chapter (https://docs.lightning.engineering/lightning-network-tools/lnd/safety#dont-interrupt-lncli-commands):

suez.py does not always run updatechanpolicy. in fact it never does unless you do use automated fee setting feature of it.
