Hoping to get some insight/help with this.
A couple of days ago I was doing transfers from Bank to Home to SV, it went smoothly but then, I used a sysbot to get their files on my pc, wanting to edit them to give them all their possible TMs and a ribbon or two, however when I traded them back to SV and Home, I noticed that some information/data was missing.
Thinking that it might've been the edits, I tried trading myself back the unedited files but then those also showed up with missing stuff. I loaded up the unedited files on PkHex again to try and see if anything was being marked wrong but couldn't see anything out of the ordinary.
File 1 is an unedited Quilava that was just transferred from Bank to SV, not even used in-game for a minute. Back in Home it showed with No Pokeball and met location of "---".
File 2 is a Quilava that was transferred to SV, PLA then back to SV. Back in Home this one also showed up as if it had been generated in SV, no trace at all of Bank's nor PLA's data.
Earlier today I transferred a clone of each into SV then back to Home without trying to trade them in SV and so far neither has lost info/data.
File 1.pk9
File 2.pk9
