NC - Excess netspeed changes!

[[ZSZ]Evil_Dragon]

I recently found the same player logged with (NC - Excess netspeed changes!).

But there never was a netspeed change in the log though. It always showed "Client netspeed 10000".

Instead one time I found: "ScriptLog: Something destroyed a LadderInventory!"

Could someone explain to me please what that means?

And also what is the problem with changing netspeed during a game? I thought it would only effect the client, now I saw there's even an AntiNetspeedHack.

Here is the log:

ScriptLog: [ChatLog][2009-06-21 17:34][Msg Spec]: .............Pure: NC - Excess netspeed changes!
