Nothing game-breaking, just found it odd:
If you spam left click (that is, to move) as well as combat moves, (only tested with QB, not sure about others) after the animal dies, the "hit" sound effect will play 3-4 more times, and IP indicators above your head appear, as well.
Also noticed it plays the "hit" sound effect extra times while in combat, also, while performing this.
Doesn't happen 100% of the time, just thought it was worth noting. Anyone else have this happen?
