Not sure if this was mentioned elsewhere on the forums, but is it just me or does the revamped version of Tri-Disaster's miasma effect not add heavy to the target?

According to the description for revamped Tri-D... "Tri Disaster" inflicts bio, bio II and miasma...

When used manually Miasma has a "heavy" effect... this doesn't seem to be the case when used with the revamped version of Tri-Disaster... I am not sure if this was intentional or an oversight, since its utility is slightly modified based on this...

Perhaps someone can confirm?

Thanks.
