So I'm noticing strange things with Logistics. I am thinking this is some kind of bug... but maybe there's a mechanic going on that I don't understand.

What do you think?

PS - I've put in a support ticket: JXT-393-28307

(the support ticket was from a different game, but in it I actually achieved -2 to Total Logistics... is that supposed to be possible?)

In the game I'm documenting below, I tried to keep very close tabs on logistics to either understand the mechanics, or find the bug.

Here's a summary of my Logistics for 6 turns in the game: turn 37 through 42.

I have only 1 city. It has an Armory and the next thing (Barracks?) which give +3 and +4 Logistics. In turn 37 I already have 1 Shard, 1 Metal mine.

Base Logistics is +4 (presumably from the difficulty setting). Pay closest attention to the Logistics from City. This is where the excitement happens.

* No units died in battle during these turns. I did get a couple of freebie dwarfs from an Inn.

41       2         +9            -1           -4            -5        -1

42       1         +8            -1           -4            -6        0            Pioneer completes. Shard next in queue

Big Questions I have:

1) Why additional +1 for Logistics from City in turn 38. Because of the city Lvl up? But there had been no additional logistics awarded when the city leveled up to Lvl 2 or Lvl 3. Is Lvl 4 special?

2) Why additional +1 for Logistics from City at the start of turn 40. The only thing that happened was that the Clay Pit completed.

3) In turn 42 I received an additional -1 to Logistics from City when the Shard became the currently building item in the production queue (even though I was charged -1 to Logistics from Resources in turn 40 when I queued it up). Did I get charged twice? If not, why did it go down by 1?
