New ContributorCritical Warning (169085): No exact pin location assignment(s) for 108 pins of 108 total pins.....
It's not an error, it's a warning (as it says) and can be safely ignored.
However, you're getting it because you didn't manually set exact pin locations (Location column is all empty from your screenshot). The Fitter picked locations for you that don't get written into the .qsf file as formal assignments unless you back-annotate them. Either back-annotate the Fitter selected locations (Assignments menu) or manually select locations in the Assignment Editor, or better yet, the Pin Planner.

New ContributorFantastic!
Is it best to keep the pins the fitter selected, i.e. are they the most optimum?

It depends on your board. Obviously, you can't use the Fitter selected pins if they don't match your board design. If you haven't created a board yet, you could use the Fitter-selected pins as a guide. It's up to you (and your board designer).

Great. Thanks.
