Blowpipe issues

I’ve put in a bug report ticket but i wanted to ask if anyone has had any visual glitches with the blowpipe. Whenever i switch to a different dart it’d still be a black powder dart, or the dart would disappear. The biggest issue is the hot key, I have to hold down the key to manually switch a dart, I used to be able just tap the button and it’d just cycle through the darts.
