When two player-characters (that includes GM chars in this case) are on the same screen, and either one runs - it's displayed as a character walking very fast in the other client.
This happens in both my UO:T2A 2D client (latest ver) and my UO:LBR 3d client (latest ver) - both when two copies of either client are used next to eachother or I "mix" the two client types.
Same thing when riding a horse and running there - horse skips around on other screen and appears to walk very quickly.
What might be causing this? We sending the wrong packets or forgetting something?
