I've noticed this while watching the Boston Major. During Virtus Pro vs IG.V game 1 the fight recap for the first blood displayed incorrectly.

For VP the Gold Change and Damage dealt was calculated wrong.
For IG.V the Damage dealt was calculated wrong (maybe more).

Correct Gold Change for Slardar would be:
423 Gold for First Blood
3x-30 = -90 (unreliable) Gold for Death
So total Gold for Slardar should be around 333 Gold.

Fight recap says he got 45 gold.
