Patch: 0.9 Multiplayer Beta.
Using the Charge skill of Druid: Werebear.
If hitting a wall, fence or similar map restriction, then i would get stuck in a loop of charging from my starting point to where i hit the wall over and over. Could only get it to stop by switching zones through teleport menu.
The charging/rubber-banding would continue even after werebear form had disappeared. No other action from the skill bar was doable during this.
