Hi! Even though this is a super easy fix, given the state of the game, they probably won’t fix it
The deck of both these files
HomecityHB06.xml
HomecityHB06p1.xml
have the following card
DEHCSPCOrganGun2xIcon
This tech doesn’t ship Organ Guns
<tech name="DEHCSPCOrganGun2xIcon" type="Normal">
<dbid>7996</dbid>
<status>UNOBTAINABLE</status>
<icon>resources\images\icons\techs\spc\hc_2x_organ_gun.png</icon>
<flag>HomeCity</flag>
</tech>
I can even fix it for you, so you just copy and paste
<tech name="DEHCSPCOrganGun2xIcon" type="Normal">
<dbid>7996</dbid>
<status>UNOBTAINABLE</status>
<icon>resources\images\icons\techs\spc\hc_2x_organ_gun.png</icon>
<flag>HomeCity</flag>
<effects>
<effect type="Data" amount="2.00" subtype="FreeHomeCityUnit" unittype="OrganGun" relativity="Absolute">
<target type="Player">
</target>
</effects>
</tech>
But I doubt this will ever be fixed before 2040
