Some of the nicknames on Lackey are not the commonly-used nicknames. Best example being the Crowds soul is called Protector on Lackey.
Using this as a specific example of my earlier comment...
The Crowds soul was passed to me solely as an image in a file named "Lost Soul-Luke 5_15.png". From that information it is difficult to know that the common nickname for it was the "Crowds" soul. The other CoW souls (e.g., Open Hand and Dull) had the canonical nicknames in the documents I was passed. I believe all such are correctly named.
Unfortunately as we learned earlier (with much pain), Lackey uses card names directly in deck files. If you have a deck with the "...(Protector)..." soul in it, and I update the set list to rename it the "...(Crowd)...", Lackey will refuse to open your deck list. The side effect of this is barring a most egregious errors, we are kind of stuck with the card names we have.
Going forward I will try to remember to ask about canonical nicknames for lost souls, before pushing an update.
