Group members remain on map after disband.
 

After a group member disbands, where they were standing on the map becomes a blue dot, and whenever you zoom in and out on the map the dot moves too... A lot of the time zoning does not solve this problem, so if one accumulates too many dots they have to relog. Is there any fix for this?

This happens on the default map as well so its not a EQ2Map issue. You'll want to report the /bug to SOE. :)
