freqQuad empty

[RhettRautsaw]

Describe the bug & to reproduce
When running -t 16 or -t 32, ASTRAL appears to complete but freqQuad.csv is completely empty. The only error reported is:

Final quartet score is: won't report because of the existense of polytomies and to save time. To get the score run with -t 1 and you can score the tree below using -q. 
Final normalized quartet score is: won't report because of the existense of polytomies and to save time. To get the score run with -t 1 and you can score the tree below using -q. 

However -t 1 works perfectly in calculating the Final quartet score and normalized quartet score.

Can you try version 5.7.8? Or is that too slow?
