Having both the leap attack native to wolves and the “wolves leap with you” node from fury leap can cause wolves to travel extreme distances when the player uses fury leap. The wolves either are a huge distance away from the player afterwards and take a long time to walk back to them, or disappear from the map completely and will only return when the player uses another fury leap.
I copied this from an old closed bug report from march last year, it still happens to me every monolith the first fury leap i use.
