Your correct I didn't do this, I just assumed the game would think that I traded it back to myself, and it does but it still needs to know who I traded it to.
Setting it to Slayer fixes the issue for my Trade Evolutions, so thank you for the help.
I don't remember if I ever needed to do this for Gen 4 games which is what I usually use PKHex for, but then a lot of those are RomHacks so I rarely pay attention to legality on those.
The Mon was found as a Gible, which is why I was surprised, same with my Aegislash becoming a Honedge when I found it as a Honedge. Doesn't actually matter in the slightest as I don't plan on de-evolving them, I was just messing around without setting to see if I could figure out what the problem was, and clearly I had no idea as again changing the latest not OT trainer fixed Machamp completely, especially when I set and went and back to it.
Reasonable, thank you for providing a solution for the Trade evolution anyways, I'll keep it in mind for the future.
Thank you so much, happy to report that this worked perfectly. Set it to 20, and then caught a new Pokemon planning on using it to evolve, but it turns out anything that updates Mable research, automatically triggers the Link Trade as well, in this case adding one more Ground Pokemon.
Some quick observations though
A) Searching in Work 3 at all crashes PKHex, not that it mattered for me since what I wanted was in Work 2.
B) Is there any way to search for Link Trade? You showed it as a link Block, but I can only search for it with F7B11ED70170BB0A, possibly because I only have Index, Value and Name, and similarly MOMIJI_COUNT_0021 fails me.
