MTX prevents freezing enemies in Offline Mode

Hey, I really appreciate you bringing MTX to Offline mode.
I was excited and bought quite a few things, but I ran into a problem.
When equipping MTX for Lightning Blast in Offline mode (I don’t play Online, not sure if this is relevant there) - when taking conversion to Cold node (Supercharged Floes) the skill does not freeze enemies.

I tried with very high freeze multi on weak enemies, works every time without MTX, but when I equip Malicious or Shattered versions of MTX for this skill, it no longer works. Even death animations don’t include “ice explosions” that normally occur without MTX.
This is a bummer, as paid content should not make gameplay worse…
