Got it, thanks. Is this not one of the changes the program ought to track, knowing how easy it is to change it idly? Clearly I did not intuit that scrolling through the GUI would change the number in the save file as well.

For any save file with valid checksums, PKHeX can be made to report an invalid checksum by viewing a different box in the "Box" tab. To reproduce: 1. Open any save file with valid checksums in PKHeX. 2. Go to the "SAV" tab and use "Verify Checksums" and/or "Block Data" to see that PKHeX calculates matching checksums upon opening the file. 3. Go to the "Box" tab and view a different box. 4. Repeat step 2 to find that PKHeX now reports problems such as "Large block checksum is invalid" for Gen 4 and "Invalid: 00 @ Region 0000 SAV: 73/74" for Gen 5. This happens even though the data is entirely unchanged to my understanding. This occurs in ver 221218 for all games I tested from Gen 4, 5, 6 and 7. They are real cartridge save files that I dumped using Checkpoint. Of course, the games load all of these save files with no complaints. This issue seems low-hanging, so I'm sorry if it's reported already or no one cares.
