Trying to Make Simple Skirmish

[Starker]

I am trying to make a very simple skirmish mission.


Mission:https://steamcommunity.com/sharedfil...?id=1704430471


Desired features:

Players start with some units

Enemies exist at start and wander randomly

No reinforcements for either side

Occurs on an existing 2v2 map

No objectives, capture points, cutscenes, win or loss conditions


Problems:

Can't find enough information on how to assign units to the player side (called allies in most skirmish missions)

Game crashes with an error when attempting to create the lobby, https://i.imgur.com/jSjeuX7.png


Please help.
