As the title says the permanent Sahha ball cannot be interacted with as soon it hits "a object" this can be even a floor, as long it’s considered to be a object. Such as in the foundry there are floor pieces to place, or platforms all over the game on which the ball does not work at all. The ball only seems to work on terrain. A small bug, but silly none the less.
I also left some feedback on the stay duration on a Sahha ball
here. It’s too ridiculously low to actually play with it.
