So far the following ships are affected by the Shipedit bug:
K-CA1K, K-CA2K, K-CA3K, K-CA4, K-D7CT, M-FUZ, R-H-S, R-SHK, A-FUZ, AN-CEA, AN-CGO, AN-MRT, AN-DDHX, AN-ANH, T-FQL, T-FQLR, T-FQS, T-FQSR, T-SCoM, T-CMC, T-SC, T-PR, T-PCR, T-PPC+, T-PFT, T-BWR, T-TK5, T-TK5R, Z-TNG
These same ships have some invalid values in some columns.
I identified these ships by filtering for non-blanks in the "End" column.
I'll keep digging...
