Summary:
"Mass Driver" column on Mining tab always showing 0 for minerals not mined locally.
Details:
I have a mining colony with a Mass Driver sending packets to elsewhere.
The Packet Content checkbox in the Display tab is ticked; I can see that the packets in flight contain six minerals.
The most recent packet shows: CB4 T1 B0 V3 S7 G1.
Of those five minerals, the colony is mining three (CB, T, and B).
On the Mining tab, the Mass Driver column shows the correct adjustment for those three minerals (-4, -1, and 0).
For the other three minerals (V, S, and G), the Mass Driver column shows only zeroes, instead of showing the appropriate adjustment for the most recent mineral packet.
Other info:
The Recent SP column shows correct amounts for all minerals.
For example, Gallicite shows -1. There is no local production or consumption of Gallicite; the -1 is due to the most recent mineral packet.
I do have a non-0 reserve setting for every mineral (which doesn't seem to be relevant but I mention it just in case).
For the three minerals in question, the current stockpile and the reserve amounts are:
V 4068 5
S 8705 5
G 2284 1000
