Description

Ham_TakeDamage doesn't make damage to player when it is triggered with entity (custom grenade) and the target is behind the wall (in range of damage).

Problematic Code (or Steps to Reproduce)

while((victim = engfunc(EngFunc_FindEntityInSphere, victim, flOrigin, g_Radius)) != 0) {
    if(pev(victim, pev_takedamage) == DAMAGE_NO || !is_user_alive(victim) || victim == id)
        continue;

    ExecuteHamB(Ham_TakeDamage, victim, ent, id, g_CustomDamage, DMG_GRENADE);
}

Usage of ReAPI with rg_multidmg_clear, rg_multidmg_add, rg_multidmg_apply makes damage as it supposed to do.
