so in the server result log it states this for each grenade kill that in the game stats at end of the round look like 9/7
grenade_kills="9" grenades_thrown="7"
Thing is, I am pretty sure you don't get 7 frags to throw

GLs are not "thrown" grenades, so the second number really should match the frag count you throw.
last round we played last night hat these two demo boys listed
