Hello, I found that AI does not recognize types of movement speeds which are set on its waypoynts.
In the latest build, for AI, they are only two types of movement speed - slow and fast.
Slow is OK, slow is slow, but unchanged, normal and fast speed they are all fast, so the AI is running like mad allways and makes itself really tired and uneffective in the upcomming combat.
I dont know if it is also related to vehicles, but it is highly possible.
