Map's "grounds" partly invisibles

In the last couple of days I tought to notice that some of the elemental ground effect were present on some tiles but lacking the visual effect.
At first I tought it was caused by some lag, making the chill effect of the chilled ground last for a short time even outside of the ground effect (usually I keep up a Quicksilver to quickly run over and doesn't pay too much attention).
The other day I was doing a Residence map with the Shocking Ground mod and suddenly I found my character dead with no apparent reason which could have hit so hard to kill he so quickly. When I went back there I saw that there were some tiles lacking the visual effect of the shocking ground, but still appling such effect on the character.

I did a screenshot and report (number 3976008744).



Another similar occurence in the same map, which I forgot to take a screen of, was the disappearance of all the ground effect on the boss floor, but after changing floor and coming back it fixed itself (but other locations, like the one in the screenshot, were still presenteing the invisible effect).

Yup, shocking ground is bugged and there is only a loose connection between the visual and the status icon.

You can also clearly stand on a shocked area but not have the effect.
