In my game, I inked, then killed ||one of the boss enemies of the heart of the storm that applied the unmovable effect on my cards|| (in one turn) and it left the effect on there
#Inking, then killing leaves the unmovable effect active

I'm pretty sure the bug is also on these cards: Ice Forge(met in 1.0.x), Ice Lantern(not met), Marrow(met in 1.0.x), Smog(met in 1.1.0), any Wild enemy(met in 1.0.x), Rockhog(met in 1.0.x).
If an enemy with some active area effect is killed by an attack with ink, it has a chance that the area effect remains
Back in 1.0.x, an attack with ink killing a Hog may add frenzy to some other hogs, but not all.
So I guess it's a chance event. Going back to the main menu then returning will refresh the effect, but you will lose lumin/frostbite on your cards.
