Occasionally when I do A skirmish vs Ostheer CPU, the AI doesn't seem to use its Sturmpioneers to build base structures right away. Instead, it uses the squads to cap points, and moments later it retreats and builds base buildings. The only units on the field would usually be 2 Sturmpioneers capping until they built the infantry gefects command later on.
Secondly, Ostheer Jagers retreat the same way like AI snipers. They will attack my squads until one bullet is fired in return, then they retreat immediatly, the same as when snipers auto retreat.
These are all the AI errors i encountered so far.
