After replaying Jazztronauts (with little to no other mods FYI) recently I have discovered that the prop snatchers cursor will become completely invisible either occasionally or with a certain thing happening (I am unable to figure out what specifically causes this). If it IS visible (I happened to tab out and back in, and it for some reason started working again) then it will display the updated crosshair over the prop snatchers cursor, which can be pretty annoying.

This doesn't make the prop snatcher impossible to use but..it is quite irritating and harder to use.
