Purple orbs from rare ennemies (which comes from plants) continue following me after dying

I don't know if it's a buff or if it's a bug, so i apoligize if it's a buff I missed in the patch notes but since 0.4.0, when i fall against a rare ennemy with the buff that creates 2 plants creating purple orbs of chaos damage (sorry I forgot the name...) the orbs don't disappear like in 0.3.0 (it was patched then) when the ennemy dies.

A friend of mine told me it didn't for him so i'm lost.
