The only problem? This week, however, is qualitatively different. I would probably start saying something. So, yes, hes not disappearing by any means. Do not be silent about this.
The only problem is different.
( z0 differ :ARG1 ( z1 problem :mod ( z2 only ) ) )
(z0 / differ-02
    :ARG1 (z1 / problem
              :mod (z2 / only)))
The only problem is different .
z1 :mod z2
z0 :ARG1 z1
