Just out of curiosity, has anyone noticed that the toon that's following my main sometimes just disconnects for no particular reason?

There are points in Mechanar, Shadow labs, Slave Pens, and other instances that unless I move them via a key, that if I use follow on a toon and sit for few seconds, they will just disconnect.

On occassion I've seen 2-4 of my toons just disconnect over and over unless i move them from follow to get out of those points to prevent them from disconnecting. I wonder if it's Blizzard or possibly my addon's that is causing it, which is weird considering the disconnects can be repeated.
