I got this figured out (I'm pretty sure).

There is nothing I can do to fix this on my end because it
depends on your operating system (
please let me know what yours is so I can provide solutions to troubleshooting on the mod main page- if you get it to work), but your solution is to play around with the delimiters of the
replace array for these particular files.
*EDIT* Sorry! This definitely isn't clear enough. I'm in too much of a hurry today it seems.
Anyway, for some relevant details:
1) The
replace array is found in the mod_info.json file. See example below. You'll see the point where the market section starts is the last line of the first example. The full portion that needs to be edited is featured in the second example below the first one.
Example 1:
{
"id":"archeus",
"name":"Archean Order",
"version":"1.3.4d",
"author":"Morrokain",
"description":"A complete rebalance of Starsector that focuses on smaller weapons, more fighters and a heavy addition of lore content. Almost all weapons and ships have been reworked to some degree and many added. Tutorials, tooltips, descriptions and hints have been updated to explain new facets of gameplay, or, use the Tactics Manual (.doc in mod folder) as a reference! Enjoy!",
"gameVersion":"0.9.1a",
"modPlugin":"data.scripts.ArcheusModPlugin",
"jars": ["Archean Order TC v0.9.1a.jar"],
"totalConversion":"true",
"replace":["data\\weapons\\weapon_data.csv",
"data\\hulls\\ship_data.csv",
"data\\hulls\\wing_data.csv",
"data\\config\\title_screen_variants.csv",
"data\\config\\exerelinFactionConfig/hegemony.json",
"data\\campaign\\sim_opponents.csv",
"data\\campaign\\special_items.csv",
"data\\campaign\\econ/aztlan.json",
.... etc
Example 2:
"data\\campaign\\econ/aztlan.json",
"data\\campaign\\econ/arcadia.json",
"data\\campaign\\econ/askonia.json",
"data\\campaign\\econ/eos.json",
"data\\campaign\\econ/isirah.json",
"data\\campaign\\econ/canaan.json",
"data\\campaign\\econ/algebbar.json",
"data\\campaign\\econ/kumarikandam.json",
"data\\campaign\\econ/magec.json",
"data\\campaign\\econ/naraka.json",
"data\\campaign\\econ/valhalla.json",
"data\\campaign\\econ/samarra.json",
"data\\campaign\\econ/mayasura.json",
"data\\campaign\\econ/thule.json",
"data\\campaign\\econ/tyle.json",
"data\\campaign\\econ/yma.json",
"data\\campaign\\econ/zagan.json",
"data\\campaign\\econ/corvus.json",
2) mod_info.json is found in the Archean Order mod folder. It is at the top level of the mod. You can open it with Notepad.See example image in the spoiler if this is unclear:
Now, for the fix:Try replacing the market section
only (seen above) with:
"data\\campaign\\econ\\aztlan.json",
"data\\campaign\\econ\\arcadia.json",
"data\\campaign\\econ\\askonia.json",
"data\\campaign\\econ\\eos.json",

"data\\campaign\\econ\\canaan.json",
"data\\campaign\\econ\\algebbar.json",

"data/campaign/econ\tyle.json",
"data/campaign/econ\yma.json",
"data/campaign/econ\zagan.json",
"data/campaign/econ\corvus.json",
That kind of thing.
Only replace the section that includes the "econ" part, however, or you may cause additional issues.
