Nah, they just upgrade the regular rail stations (lvl2and up) to HS rail stations. They can do that now that the world has been patched to allow it.

If Fuel and population allow you should keep your truckstation in the Capital SHQ as high as possible.
Just using truckstations you'd start losing logisitics capacity after about 12 hexes distance. This can be extended with a supply depot once (so no daisy chaining them) and using sealed roads.

Has anyone figured out how to tell how much to bid for a share? Like if I'm flush with cash I might bid 4 or 5 times the initial bid. However in recent games I got completely outbid by the AI, like they bid 4 times more than I had in the treasury. That's fine, I question how they consistently have ...

It's somewhat tricky to get the government profile up with the MTH events. Though if you push your taxes high enough you'll regularly get the 'People are protesting against High Taxes event' which has the options to push more government profile.

I was playing a Meritocracy, Government, Mind as main ...

You might also want the MTH to make a makeshift port to reduce the penalty for supplying units across the sea without a port.

Well Quad-MG mechanized or not is lethal to any infantry, so jump infantry isn't that much more vulnerable. I suppose if you were designing some Infantry specific OOB that would be good in difficult terrain like mountains and cloud forest adding some Jetpack infantry might give them a bit more punch ...

I do agree that it seems a little nonsensical that Freefolk seems to team up with hostile aliens/slavers/surviving AI to attack the player. Some of these should be antagonistic to each other.

After looking at the design logs after completing a game I found some mismatches in the recon stat of a couple of vehicles.
The Buggy is classed as an APC,
The Heavy Tank and Tank Destroyer are classed as Buggies.
I asked about it on the main forum and this bug seems to be present in the open beta ...

Playing in 1.11b
Finished a game and I was looking around the design logs of my units when I noticed an oddity.
Apparently Buggies are classified as APC,
Tank Destroyers and Heavy Tanks as Buggies
Other vehicles seem classed correctly, though I didn't get all the way up the tech tree. I don't know ...

It's a bit difficult to say, from the numbers shown I'm guessing there's a bottleneck to the north of your SHQ. Is the truckstation at your SHQ functioning at full efficiency and upgraded as best as it can be?

Your logistics network looks fine. If it becomes dire you could set your SHQ to commit ...

You should be able to build railroads from tech 3 and up. It's just available no need to research. Unless you mean High Speed rail because that's quite a bit down the tech tree.

I concur, after looking it over it seems your logistics system is at its limit. Similarly I recommend upgrading the truckstations in phases as metal allows and when possible to start setting up a rail station at the SHQ to feed some rail heads near the front.
Your empire is getting to a size where ...

Maybe the road itself is just borked. Because for it to somehow not see it as a viable or more expedient route for supplies in that direction is just silly. I suppose you could remove it for a turn and rebuild it the next as a test to see if that makes a difference but that's about all I can think ...

Certainly a weird situation. The few times I've seen something similar is when either the truck station is not working at full capacity or it ran out of fuel for a moment in the turn resolution, but I'm presuming that's not the case here.

You need to either discover and develop the RPG Infantry with the Staff council. Or customize an existing formation to add RPG troops.

Strange, the only time I've seen sentinels spawning like that is when you fail the event with the supercomputer/AI.

A supply depot wont do much beyond extending the range a bit. Setting up a truck station at the halfway point could help but at present it seems there's just not enough logistical capacity between the two cities that could be more easily solved by upgrading the truck stations in the cities if ...

In the MNG screen if you expand the inventory reports of the zone in question, it should show you if any recruits were produced and how many could be delivered to the SHQ. Beyond that I'm not sure, what else to check for.

I suppose the first question is. Does your new zone have the logistics capacity to get the recruits to the SHQ? Is the zone happy and loyal enough to have people join as recruits?

Yup, it's been that way since the start. There's been calls to make the normal train assets upgradable to HS train assets but so far this is the way it is.
