Rawcodes don't work with upgrades.

How come whenever I try to use rawcodes to reference stats in descriptions of upgrades it always ends up just saying like "Increases attack damage by 0." in-game. I don't have trouble with ability/item/unit descriptions. What is different about upgrades?

It seems you can link only non-custom abils/upgrades... for me, I had same problem and ended up with this.

That's lame.

It works just fine for me, post one of your tooltips.
