Bumping this over making a new thread, as this issue persists in version 0.9.023.
When saving or loading save data, "short":"FrostwyrmName" is removed, causing the game to return Frostwyrm in place of it. Going back to an older save and naming it does not add a new entry into the save to replace the short entry either.
If relevant, my observations and tests stem from the local Windows versions of the game.
