Skill Indicator Bug
When you play on EUW and on any other server (i.e. NA, JP, etc.) your skill indicators on those servers will get messed up. A fresh install doesn't fix the problem nor first patching the NA client and then going on EUW, it always messes up the NA skill indicators the moment you have EUW + another region patched.
This first happened when the Hextech system was introduced to NA and then later on EUW, but since NA got it first it seems to have bugged something out when playing on more than just 1 server.
All skill shot indicators (like Bard/Morgana Q) will no longer show the skill path indicator, but only give you the range circle as well as a point and click mouse cursor. (as if you would manually click on
)
