Hi there, Thank you for reaching out. We understand that the Knock 'Em Down triumph doesn't seem to be tracking multi-kills. We can imagine the impact this may have had. If you continue to experience this, then please consider using your platform's share feature to capture a videoclip of what you're experiencing. If you record such a clip, you can upload it to a site like Imgur or Youtube, and share a link to it here. We'll then investigate this further.
