1. The key change seems to be the problem here.  Something about it 
makes the spacing for that last quarter note bad.  Simply removing the 
key change and tweaking as in 2. solves the over the bar line problem.  
The spacing of the quarter note is still not as good as it could be.  
Also the problem goes away even with the key change if you can put 
another measure on that line.  See attached example.

2. It may take more tweaking as in:  s8 s16\! s16

3. I guess ferSlur is a construction of yours.
