The productivity bonus tech doesn't work at all.

In mining_drone:process_return_to_depot() from script/mining_drone.lua you calculate the productivity bonus correctly, but then don't use the variable.

a simple stack.count = stack.count * productivity on line 225 fixes it for both supplying it to the depot as well as the production statistics.

more than we don't see the bonus that we should have in the menu of bonus in-game, for the speed and productivity.

can we at least get this fixed? In my testing drones really dont benefit from their own productivity research.
