This could be a lag issue, a disconnect issue or a "track user" issue. Twice now I've tried to track to someone and found myself flying off into some point over the ocean. The pillar is there so my client obviously thinks I'm actually moving towards my trackee.
After this my avatar continues to fly away from land no matter what I press. I let it go for about 10 minutes last night with no change.
on my way away from land I noticed that my map was only showing a single cell of land, the land that my
home is on, and thus the land that my tower is built on.
I'll post again if it recurrs. The first time was the day I first logged in, then again last night.
