Im having the same problems.

When i use the /follow command my character will run the complete opposite direction

I was having major problems getting the two characters to do things together.

I do not think this is a lantacy issue but an.. anti-bot issue.

This was in the starting zone for Orc/Troll

P.S I have 300ms and in BG's etc. when i have my 2 level 70 characters

They follow each other normally and everything is fine
