[Bug] Fireball enchantment doesn't benefit from Enhanced Fireball upgrade

It wasn’t supposed to have increased radius pre 1.1.1 I think, since the Fireballs exploding from enemies’ deaths didn’t travel.
But now since there is no distance requirement to the Enhanced Fireball upgrade, it should benefit from increased radius. But it doesn’t.
Also, Fiery Surge skill doesn’t work.

Has this been fixed?

Fiery Surge does work for me: i get the buff and mana regeneration in the stats increases when this buff is active.

Enchanced Fireball is not supposed to work with Fireball Enchantment as it is not listed in the enchantment Modifiers section.
