Jumping NPC bug

i have encounted npc's that seem to run and jump into there spot then warp back a bit and repeat. idk if this has been covered before in another post.
hers a link to video http://www.youtube.com/watch?v=R2H7N0Fa37o
srry bout the bad quality

afaik You've got a corrupted .dat file, delete it and re-install and everything should be fine. Or live with it, whichever one floats yer boat

Most likely corrupted file... but what if its test for animations for GW2 jump system? Plausible, but more likely to be a corrupted file.

Looks cool,
Keep the .dat file

Nope, its a corrupted .dat file. Another funny glitch of this is that the characters standing still will look they were hit by a bus and fly through the air 10 feet and landing like a ragdoll. Quite funny, until Guild Wars stops launching.

You'll need to reinstall the .dat, so I've moved you over to the tech forums! :P

although not in the video ive also noticed the xunlai chest spinning on some occasions
would this also be because of the .dat file?

ya how do people corrupt the dat file?
i wanted to do that just to see what would happen.

Possibly getting disconnected while the .dat is being written to? It's one of those annoying things that "just happens" sometimes.

Yep, animations seem to be subject to .dat corruption more so than other areas. It may be and most likely is the structure of the .dat system.

That was rather amusing to watch. (Un)fortunately my .dat file has never been corrupted after three years of play.

Thank god some one asked this question, Mine have been doing the same thing for three days... i thought it was funny at first... but now it's getting rather annoying I'll try the .dat thing and hope it works!

This occasionally happens to my character, and any hero/henchman/other people.

Is quite amusing to see what appears to be 8 people shadow stepping from enemy to enemy... For a while >.<.

-re-install-.
