Upgrade Bug? v119

[Tids]

When my Persian Immortal travelled to a goodie-hut/ruins, he got the upgrade bonus. However instead of upgrading to a Pikeman, he got turned into a Levy, with his shock promotions turning into trenches promotions.
Is this class change intended?

Thanks, fixed this. I'm not sure why I set spearmen to upgrade to levies... maybe put that edit on the wrong unit.
