Hello, VisualTech48 here. I have noticed (Not big but annoying) bug within using the Snap Settings.
Although my snap settings are like:
Unity addes 0.001 everytime I use this snap feature. However the main issue this represents is with rotation, as to rotating the whole level at 0.001, which yes, it looks like no big deal, but even when I duplicate an object, every time I do so, it adds 0.001 to everything in transform (Sometimes sparing the Scale)
