System Gameplay error bug
 

This happens me frequently, everything is broken but only you will experience it others don't, if you experienced this kind of bug, you should know if you move you will become invisible and everything is broken, please fix this error, It happened to me like 10 times, it's kinda annoying lol, not sure if the bug error happens in mobile or Ios, but I'm sure alot of PC players experienced it

This sounds like it's just an issue with the animations for walking not loading in, Since things load on the client side that's why nobody else sees it. Just relog, Nothing really devs can do about it. Unless they make it so the flash can store the data so you don't have to load everything up every time you go on the PC graal, Which i don't think is possible anyway.

I think this may be lag.
