(EN) When comes to careers in the treasure chest , he destroys it , but all the things that were in the treasury chest disappear.

(Ru) Когда карьер доходит до сундука в сокровищнице он его разрушает, но все вещи которые были в сундуке сокровищницы исчезают.

I remember in older minecraft (maybe 1.2.5) the quarry picked up the loot.
Has the chest dropped the items, and then they've despawned or the chest didn't drop the loot? What's your BC version?

Version of Minecraft 1.7.10. BuildCraft version 6.2.6 .

I have checked the work career . Put in a chest diamonds and switched careers. Careers destroyed his chest and sent through pipes to the repository , but diamonds disappeared .
