Okay that has sorted it however after playing, it seems that units cannot get a hit, this effectively breaks the combat as it makes it impossible. It may need more work but I think it is technically working, it simply means that every attack is a miss. The only thing that comes to mind is that the variables of dodge and accuracy have to be set to the units? I am unsure if that is the issue but it’s is what comes to mind.
EDIT: I have found the accuracy and dodge variables in the unit details. After setting these to numbers, it is possible to attack units ingame. (I’m glad I was right, makes me feel good to fix this myself, sorry to waste time).
