[CS241] Odd Parsing Problems

When printing out some sentences, I came across that fact that VP;2xxx
has actually created some mistakes in detecting paths.  Take for example:

 senegal complied with a french request for assistance sent a small
contingent as well

(S1 (S;041 (NP (NNP senegal)) (VP;270.82 (VP;82 (VBD complied) (PP (IN
with) (NP (NP (DT a) (JJ french) (NN request)) (PP (IN for) (NP (NN
assistance)))))) (VP;82 (VBD sent) (NP (DT a) (JJ small) (JJ
contingent)) (ADVP (RB as) (RB well))))))

You will notice that there are three VP indicators, however, there are
only two actual VPs (This sentence generates two *VP-VP paths) so that
the VP-CC actually fouls things up (at least in this case).

Has anyone else run into anything similar?
