Creeping Death bugged?

I decided to start playing around with the Creeping Death again recently and I noticed two things about it that seem to be broken:

  1. It cannot proc melt DOTs despite the item card (at least on the one I have) saying it has a 29% chance to do so
  2. Sticky projectiles sometimes won’t home in on damaged targets- this seems to happen mainly when they stick to walls but it can happen to ground projectiles too

Both of these issues (especially the first one) hurt the Creeping Death a lot and as a result it’s very underwhelming even with the 200% damage buff it received recently.
