I've found a bug in the map. The church (the one offset to the right from the middle if there's more then ONE church.) gives you the option to spawn units if you got a unit in it.
Was PE and it was saying that I could spawn Volks ect, So I assume its one of the buildings from the ToV campain and you've neglected to remove the unit spawning attributes to it. Luckily, They have MP costs, and in a mod with no resource element I couldn't luckily, but it looks completely outta place xD
Would get screenshots ect but I don't know how to 1v1 a bot so I can quickly jump in to show you...
If you need more info, Send me a PM and I will try to explain it better.
Edit:- Just noticed there is only one church in the map so that makes it easier, but I thought I just edit the picture in the OP so its an idiot guide to it
Edit Edit:- I'm pretty sure it was the church, Slightly unsure now D:
If its not. Then ONE of the buildings in the map is bugged and GL n HF finding it
