Topic: NPC movement - Client/Server Sync issue?

For the last few weeks I've been finding that the npcs are moving strangely. They take a few steps forward then warp back a little so they have this jittery movement. When they die their wrecks are never exactly where they exploded usually a square or two away, they also seem to walk into walls a bit before teleporting out.

To me it looks like the client and server are calculating the npc locations differently and are therefore out of sync.

At first I thought it was lag but after weeks its not gone away and my ping is at a steady 55-65 ms and there is no perceivable lag in any actions I perform in game.

I've tried redownloading the client in case it was corrupted somehow and this didn't help.

Heres a tracert just in case:

Re: NPC movement - Client/Server Sync issue?

I think it's similar to how the client predicts other player movement (so they can sometimes look like moving thru solid objects).

Re: NPC movement - Client/Server Sync issue?

Got the same issue, and it wasn't the case before the new IA patch.

D: How come you don't roll on Saturday, Walter?
W: Saturday, Donny, is Shabbos, the Jewish day of rest. That means that I don't work, I don't drive a car, I don't f***ing ride in a car, I don't handle money, I don't turn on the oven, and I sure as sh*t DON'T F***ING ROLL !!
D: Sheesh.
W: Shomer shabbos! ... Shomer f***ing shabbos!

Re: NPC movement - Client/Server Sync issue?

I've seen them warping too, and it doesn't happen since the last patch so I consider this fixed.
