I've been trying to debug this on my side, but haven't been able to figure out what causes it as I keep the windows firewall off, because I find avast to be much better at the job.

Basicly, just as the title says, at random I will lose mobility. This is to a point that all movement keys, before and after resetting/binding new ones, will not respond at all. However all other keys do respond. So I can still chat, make bug reports, open menus and such. I can even still use health pills, though this appears to have a bit of lag behind it. I have had this happen to me while in the middle of combat, resulting in death because the monsters can just keep doing their sudden laggy swings. And twice so far while in Haven, though while in haven there is no noticeable lag like while in the clockwork.

When this all happens my connection appears solid, being all 5 bars. During one instant the lockup continued AFTER restarting the game.

My computer is a custom build off Youtube http://www.youtube.com/watch?v=O6olutcuXHc&list=SPADA5B91FFC11D251&index=5 (This one) with a Windows 8 operating system and a wireless adapter because I can't set up a wired connection. So I know it isn't a problem with my PC's specs.
I do know in the past SK hated Windows 8, flipping out when I tried playing....
