Problem conclusion

• The algorithm used is very complex and runs through all possible
  paths in order to create the report. And when setting high
  values for depth, the resulted report can have more than 40k
  pages. Part of the problem comes from the fact that the
  algorithm builds all possible paths and only after that checks
  if they are valid.
  
  Solution: We improved the performance of the algorithm, by
  checking paths at an early stage and removing them from an
  incipient step if they were invalid.
  

Temporary fix
