Herald of Blood and Blood Pustules bug?

Hi, is it possible that Herald of Blood prevents the activation of Blood Pustules from the Corrupted Huntress? When I have both active, only Herald of Blood seems to activate, and I don't see the Blood Pustules debuff on enemies. Is it intended that you can't use both together with the Huntress? That would be a bit of a shame, since Blood would be less rewarding compared to other playstyles, wouldn't it?

OK i have look on it. The Herold of Blood let corpsesd explode before the Blood Pustle can take effect. I think it is a bug then when not it makes a blood build very week =/
