Weird multiboxing bugs?

I'm only level 20, but there's already two bugs I encountered..

Twice I encountered a monster mob that was only visible to one or two of my characters and didn't exist for any of my other characters. (Without noticing any form of lag or anything like that.)

The first time (Mulgore) I encountered this I wiped blatantly. xD (I was level 6 and like, oh my god I can't kill it or see it with my main! While it butchered my four alts.) Second time I was prepared though (Which was in the Barrens). xP

And once I had the flying mount bug on Kalimdor, but it only showed the bug to some of the alts, not to all. :S

Could be your graphics card. What you rocking?

That's almost assuredly lag artifacts. If you run a software firewall, set your WOW.EXE process to LOW priority and it should fix it. If you're running multiple clients on one machine, make sure you do the background FPS setting trick other folks have mentioned. (maxfpsbk?) Also, what internet connection are you running on?

It happens, your other clients 'de-sync'. The mob isn't invisible, it will be far away (on the clients that can't see the mob) standing still. It happens even if you use 1 client at times. Although it shouldn't be a frequent thing.

*edit*
Just switch to a client that can see it and get your followers to assist, you can kill it - it will look like the mob is losing no hp, but it is :D

I've occasionally had different characters see others as not dismounting after a flightpath. It only happens on their screen, and goes away after a bit. Just kind of funny to see. Also occasioanially my mages follow flips out and every time I hit the follow button "You have stopped following XXXXXX" immediately pops up.

been there.. done that... lol, its frustrating.

Some areas are worse than others in the game, like there are invisible transitions between areas or something that arent synching well. One great example on a laggy day is the front door to Blackrock mountain. I spen't 50 to 58 in there on my mages, and can remember at least 50 times one of my guys losing track of the group as I go from the hall into the big open space with the chains. Another bad spot imo is the Oshugan Area of Nagrand.

Ever have one of your characters suddenly start running forwards, or strafing in some direction? No matter how I dualbox, one computer or two, no matter what way I do it, keyclone synergy octopus AHK multibox or no keybroadcasting at all, it happens like once a month.

People on this forum were trying to hunt that bug down last year but I lost track of that thread
