Subnet placement in campaign.loc file
 

Cleaning up the map for V2.1 of TMO Update.

Noticed an AntiSubnet01.dat file/assume can place a subnet in as scenery vs placing in campaign file?

i believe that the .dat is used to set the features of an anti-subnet.

if you want to have that anti-subnet appear as an impediment in SH4 you would need to add it to one of the campaign mis files, like Jap_Minefields.mis, which has mine fields rather than anti-subnets.
