Odd characters showing up in output screen

Periodically, I see odd characters in the output screen replacing the text that should have been there. Fairly often, it happens when I type something that's sent to the world.

Nobody else sees the occ characters but be, so it's in what gets displayed on my screen, not what's sent to or from the MUSH.

Most often, the characters are 'http' but occasionally are high ascii characters. So far, all occurrances have been four characters long.

Most recent example:

sent to world: my cablemodem
received: m[ÁpÉblemodem

Seems to be happening on the forum as well! :)

Strange, is this happening to anyone else? Sounds like a MUD outputting problem, or transmission error. Try doing a packet debug if it happens often enough that you can reproduce it inside 5 minutes.

Here's a packet where the problem showed up.
The name of the player speaking is supposed to be "Cerekk" but four characters in the middle of his name were changed to garbage.

Incoming packet: 3995 (78 bytes)

The packet debug is written out very early in MUSHclient's packet processing (right after decompression, if applicable) so if the junk is there it is very likely it arrived like that. I suggest the server has a bug where it is corrupting its output. Try a different client. I doubt MUSHclient is doing it.

A few versions back an obscure bug was fixed that might be related to this. A buffer was being shared between worlds, that might have accounted for this behaviour.
