Phahd Scaffold randomly not counting as having killed Kuva Clouds

[OneArmedViolinist]

This seems to happen about 25% of the time.  I launch the secondary fire of my amp (Phahd scaffold) at a kuva cloud, and it connects.  The cloud vanishes.  But I do not get credit towards my X/4 braids killed.  I have seen this happen with a direct hit and with a secondary (after at least one bounce) hit.  Most often, when this happens, the braid continues to reach towards where the cloud was destroyed for a few seconds before it gives up and spawns in a new cloud.  Haven't had this render a siphon impossible, but it does slow the process.
