Hi there,
Can you please record a short video showing the issue in the Elven Ruins? Are any of the actors below zero altitude? It might be a calculation error that is causing the cannon to look downwards, for instance, if the end position is below the tank, and you’re using find look at rotation, perhaps you want to constraint the values of pitch so the cannon will never look down. Please record some videos or screenshots and I get back to you tomorrow morning.
