[2020] [Bug/Glitch]Max item quantity exceeded?

So I have some normal apparel box keys. Decided to throw them into the "blender", and then this pops up.. https://i.gyazo.com/653131b9f22c9baf...980f3d0d75.jpg

I run it in 1440p, and the img code made the picture ginormous, so hence the external link XD

I don't think I've ever had this happen? I did a quick search and nothing seemed to pop up.. so... lucky me?
