Hi PaQ, it's no trouble, and it is helpful for me to know when some of the new v2 things are causing confusion in certain situations.

Can you possibly post the model so I can take a look at your trimmed circle?

If that trimmed circle is on the same plane as the center point you snapped on to, then it is supposed to snap on to it, so that could be a bug or perhaps a tolerance issue where I'm using a slightly too tight tolerance to suppress off-plane snaps.

It may be something that I can tune up if I can examine the case more closely.

EDIT: Oops, I see that you did post it, I'm not sure why I didn't see that, I will take a look.
