KubeJS script that will allow you to add custom tasks to FTB Quests to detect that the player has acquired a specific Forestry bee species.

beetasks.js

// USAGE:
// In FTB Quests, add a custom task type. Add a tag that starts with "beespecies_" and ends with the name of the species.
// There are some limitations to the tag string contents, so everything must be lowercase, colons and dots can't be used.
//
// Examples:
// beespecies_speciesforest
// beespecies_speciescommon
// beespecies_specieslordly
