Milestone Harvesting (Greek) has wrong benefit

[Sleyver]

My brother @Forest and me found out, that the Greek Milestone "Harvesting" with the description "Decreases Storehouse tech cost by 15%." decreases the storehouse tech cost much more (63%?) then in the description written.

I can't proof this, because I have "Foraging" selected.

No reaction here? Is something wrong with the report?

Thanks for fixing this. Still: any chance to introduce a consumable or another option to reset milestones?
