I've recently started mission making with ALiVE, and I've noticed that after the war drags on for a while (about an IRL hour) default factions will start spawning instead of the forced factions. For example, an invading commander with its faction forced to OPFOR CUP_O_TK and synced to a military logistics module with Air Transport Assets set to "Faction Only" will eventually start to replenish its forces with default OPF_F CSAT units. I've checked, double checked, and even triple checked each module to make sure there are no typos and spaces in the faction fields.

The mil_placement and civ_placement modules spawn the correct factions.
This issue has happened on both of my ALiVE missions.
The first mission has RHS US Army invading an RHS Russian MSV occupied Altis.
The second mission is a three-sided civil war between an invading OPFOR Takistani Army (CUP_O_TK) with low initial forces, an occupying BLUFOR Takistan National Army (UK3CB_TKA_B) with high initial forces, and an insurgency comprised of INDFOR Takistani Locals (CUP_I_TK_GUE) with very low initial forces.

In both of these missions, the invading faction's forces are replenished with the default faction. In the first mission the RHS US Army begins to receive NATO troops and equipment, while in the second mission the Takistani Army receives CSAT troops and equipment.

The module configuration for the Takistani Army is as follows:
