I’ve been experiencing this problem in almost all my games. I lose control of my character and it starts to move rapidly around the map, even going through walls. It lasts a long time and completely stops me from playing. I’ve searched around for this ‘‘bug’’ but I didn’t find anyone with the same problem, or I’m not using the right terms.
What you are experiencing is severe connection latency in your game. If there is a delay in the input and output of the game, the game client will try to recorrect the position and status of your hero whenever it receives new data from the server causing the effects that you describe. You can check your current latency by pressing Ctrl + Shift + R and checking the Latency stat which will appear in the upper left corner of the screen. If the number is going into the 200’s or higher, you would be seeing the problems that you describe.
Refer to this troubleshooting guide to resolving any potential issues on your end that can cause increased latency in the game. If you need more help, I recommend starting a new topic in #technical-support.
