So I’m not sure if this is intentional or maybe I missed something in the patchnotes but since 0.8.3 I’ve been having issues with Shurikens disappearing when hitting certain enemies like Voidleeches, Voidforms and some other worm-type enemy that explodes on death.
I’ve specced both Blade Shield and Ethereal Blades.
Edit: Voidfire Maggots do this as well.
