On the map market on execution i have seen multiple times that there is a healing arena, red or either blue that is healing you but there is no healing station there.
I made a screenshot of what i mean.

I believe the issue is not that there is an invisible healing station, but the visual overlay healing pattern just remains, with no healing effect.
yeah its a bit of a serious issue. wasted quite a few abilites trying to kill the health station and anyone close to it only to find there was no health station.
also makes new players not familiar with it being a visual bug trying to stand in the circle to get healed and not.
