Persisting consecrated ground buff

So I got to the first encounter with cavas, in the coast. I did the memory, using only zombies and Pyrifying flame. I was killing some mobs and must have been standing on consecrated ground when the encouter ended.

As i got back out i noticed that my Zombies have the buff from consecrated ground, even when they are not on it. This is a buff ;D.

I managed to remove the buff by reloading the area, I also tried making it occur again, by spawning consecrated ground under me before trying to get loadscreens. I could not do it by recreating the same area(hold control on waypoint), cuz the duration was to low or me being hungover and slow. I could also not do it by changing area through doors, like from the coast to the small island with the coldboi.

Planning to try again next time i see cavas, to check if it was a one time thing, but yea.

Here is a few screenshots for some context:

K cant replicated it through cavas by spawning the ground under me, just before it exits. Douple check it still.

additional small thing, pyrifying flame is inconsistant with smashing urns and corpes and stuff, its annoying, first boom should be able to do that.
