I found that I only have 1 sector error. This causes the whole partition proof faults .. In my opinion 1 sector should not result in failure of the whole partition/deadline. ### Improvement Suggestion ```text When its windowPost , your code just call fn "generate_window_post" and leave it alone ... "Proving check --slow" call fn "generate_single_vanilla_proof" to check status .. "generate_window_post" real code inside "RUST" and "filcoin_ffi" not in "lotus" The real code inside "Filecoin_FFi=> genenrate_window_post or fi_generate_window_post " NO TRY/CATCH!!! Lotus team should add try {} catch {} function inside ! ```
