Crippling/Shuddering Movement Animations

[Sugar Min.5834]

Hi. Every few months this is happening. When I login to the game, suddenly my characters will start walking or running with a crippled shuddering animation. Even when moving backwards or on a mount. I have to jump forward and continue walking/running and that will remove the glitched movements. But the moment I stopped and  then moved again, the cripple and shudders came back. Many times over the years, I wrote to support for help and usually within 24 hrs the problem is fixed. But a few months later, the glitched animations came back and I have to report again.

I cannot understand why this problem persisted after so many tears, like there is no permanent solution? As for my side, no I did not do anything in particular to my computer that is why I cannot understand what is wrong. Does any one of you guys experienced same problem? I did data repair too but that didn't help at all.

Thanks for reading.
