I think you have a food shortage and your confusion comes from the fact that emergency food consumption does not show in the food stock tooltip.

This turn's consumption was equal to:
709 + 1183 + 950 + 1204 + 1250 + 388 = 5 684... This is equal to the start of turn stockpile.

This is correct ...

Logistics points are never converted into a different type. However, once placed on the map, truck and rail logistics points are completely interchangeable, so supply brought to the end of a rail line by train can be delivered the rest of the distance by any locally available truck LP just fine.

By ...

My best guess is that it's the chance of gaining a skill level upon spending a point of XP.

The existing list of OOBs is incredibly bloated with slight variations of pointless garbage. The only existing OHQs I'd keep are pure armor, light infantry, (heavy) MG/RPG/grenadiers, and motorized/mechanized variants thereof. Everything else in the list is either useless or can be trivially ...

I checked out the save, and I can't see any reason why the transfer between the SHQs is unavailable either. There seems to be a contiguous line of unspent logistics points.

The default chance of a hit being a kill is only 12%, so combined with the limited window of opportunity to engage a target before it retreats off the field, it can sometimes take quite a lot of effort kill off an unit without encircling it (which is obviously not possible with sea creatures).

This is the first time I've seen anyone claim to have evidence that shields have ever offered any protection against asset damage. The only mentions of shields in the changelogs are related to personal shields, not shield generators.

Do you have enough energy storage? Energy in excess of what you can store can't be used. You get a low amount of energy storage from population, but it's not sufficient for an advanced economy.

You can address this by building the energy storage assets unlocked by the Power Banks tech (right side ...

Maybe it has to do with the logistics production delay (manual section 5.11.3.1.)? If so, it should fix itself next turn.

The logistics refocusing mechanic causes the loss of at least 25% of logistics points whenever logistics passes through another logistics station of the same logistics type (truck or rail) (scaling up based on the amount of AP the logistics has expended and the amount of previous refocusings), but ...

A subunit, which is the smallest increment of troops tracked by the game, is 100 infantry or 10 vehicles or guns.

Hitpoint bonuses from entrenchment and from being unspotted are multiplicative with each other, like most modifiers. Entrenchment has no effect on whether something can be spotted.

For the purpose of spotting units, hide points are deducted from the amount of recon in a hex. This can lead to ambushes, but it also reduces the likelihood of individual defending subunits being spotted in combat, and according to the manual, unspotted defending subunits can have their HP ...

If you want units to turn down replacements of a certain quality but keep any they already have, you have to set that quality to Tolerated in the unit settings. They will also swap Tolerated quality models for Accepted ones.

When subunits are transferred to an unit that already has identical models ...

In the present turn (today so should not be related from the few days ago update), a couple of my jnits at the front appeared without icon and with a 0 on them. they were not attacked. Clicking on them reports them empty (also no stats nor HQ picture).
This is almost certainly because you've set ...

So the player was eliminated because their last city was taken by rebels, but somehow the player's former regime took back the city while under AI control? That does seem very strange.

For comparison, when a player is eliminated by resignation, their regime becomes an inactive rump state, all their ...

A bunch of people in the Discord server has mentioned that their troops are starving to death, not because the logistics are insufficient, but because ammunition is prioritized before food.

Now, I know SE is not quite that granular, but if I was the logistician I'd prioritize it the other way ...

That depends on whether Midcore Logistics is on or off.

If it's off, logistics must be split at intersections, but if the branches join together at a later point, the logistics points will be added up.

If it's on, the full amount of available logistics is sent into every branch at intersections ...

Yes, but note that the logistics deliverable to any single target branch is limited to 100% either way. For example, a city can't use more than 100% of produced logistics, because when it uses it, the proportion deducted from its own hex is 100% (and logistics points originating from the same asset ...

Have you checked that the mech artillery model is set to a quality level that's accepted in the unit's settings? If it's only tolerated, then replacements of the model won't be sent out. Though by default, all quality levels are accepted.

Like with regular techs, in most cases, the effects apply to any new model designs you create. I don't know whether the effects show in MNG -> Models -> Techs like with regular techs.
