Tried Alits and Stratis, vanilla civilians are spawning fine.
Altis with LOP civilians (LOP_TAK_Civ) works aswell.
CUP Chernarus and Lingor A3 seems to be able to spawn vanilla civilians fine also.
No vanilla civilians would spawn on Kunduz or Esseker with or without TOAR.
Spyder addons civilians work on all maps so far.
Also getting no radio warnings at all to indicate the problem.

so it seems to be a specific few custom maps that have the problem.

We are using CUP

On Esseker I have this problem as well. Doesn't affect military units, but civs men do not spawn even when using vanilla. Just the vehicles. I am also using CUP for the map base and it's the only map that is supported by ALIVE I have issues with.

I have done some civ placement module testing on several maps and have noticed problems on larger maps. On Altis most towns get civ spawns, but not all. This is true for civ placement without a TOAR. If you confine one of these no spawn areas to a small TOAR, then you get spawn. Messing with different size and numbers of TOARs have lead me to believe that somehow the civ placement module gets overwhelmed. If the number of settlements is too great, some are simply left out. On Takistan, you can cover about half of the map with consistent civ spawns. If you try to cover more than half, large gaps then appear.

I was on a limited device earlier which created a less than helpful post.

I just did a clean test on Altis, no mods except ALiVE. I put in the required modules plus civilian population and civilian placement. The parameters were default (no filtering both) except for placement level, which was set to extreme. No TOAR was defined.

The results were some major settlements were not recognized by placement module. According to the debug info on the map, the settlement just wasn't recognized. For a quick example, there is a settlement near the ruined castle named Oreokastro that is not recognized. Its a fairly sizable place.

Obviously when I run Takistan(CUP), I am using mods. In that case, I tested a great many parameters. I tested default tests, where I ran module defaults. I ran different TOARs and no TOARS. I didn't mess with the filters much, because I was not seeing settlements populated in the first place ;-)

In Takistan, it did recognize all the settlements that I checked. However, as I stated, it wasn't consistent with how it spawned civilians. It did spawn ambient vehicles without problems, though.

To be very specific on Takistan- I setup a civilian population and a placement module, the placement didn't have a TOAR. I went with default setting first and noticed many settlements were not populated at all. Some were and some weren't. The fairly large settlement near the airbase was barren, though the module detected it. It did populate the smaller settlements on either side of the deserted one, though.

This is where I started running various tests to figure out the problem. I then setup the placement module with a TOAR that encompassed a few settlements near the airbase (including the one that didn't spawn anything) and that was it. The result was that it perfectly spawned civilians in all the settlements within the TOAR.

So, then I added another TOAR to the module, one that included a few more settlements- it still worked perfectly. BUT the more settlements that I added to a TOAR, the more sparse all of them became. It reached a point when I covered half the settlements on the map with a TOAR and then the massive gaps began to appear in the TOARs (the same gaps that appeared in the no TOAR test).

This is what lead me to the conclusion that the civilian placement module reaches a saturation point where gaps begin to appear in the settlements, both in density and in location. Having said that, Altis seemed to handle the civilian modules much better.

I suppose it is a problem with Takistan. I also noticed the military civilian objective modules were affected too. The spawning methods showed the same avoidance of certain areas. Perhaps something was messed up in transition to CUP.

I haven't played the vanilla campaign, so I don't know what should or should not be occupied on Altis, but there were other settlements not indexed also.

I wonder if my problems with Takistan come from some sort of data corruption using Steam Workshop. I have heard of people having severe problems with CUP maps that are downloaded that way.

I started the game with only CUP Core, Maps, and ALIVE (plus CBA I think). I started a clean Takistan with only core Alive modules plus population and civ placement at default settings. I got Highhead's results, everything seemed to work.

I am going to see if I can pinpoint when I break it.
