Features & Improvements

  1. Fixed an issue the Choice Simulator where the same scenario would appear to give different results.
  2. Fixed an issue with Genetic Search where removing the none option results in an error when running the simulation.
  3. Fixed an issue with running WTP scenarios when there are conditional price tables.
  4. Fixed an issue WTP creating scenarios when there are conditional price tables.
  5. Fixed an issue where a prohibition is reported in the scenario if both alt-spec rules and conditional price tables are used.
