I have a phantom tower: a tower I placed, later vanished, but still counts as active.

Data for your devs:
RK2 ( rimor )
Omni
Bigstupid, lv 148

Dates are estimates:
Dec 3: I placed 2 towers in a zone in MilkyWay controled by Project EDEN.
1 guardian tower and 1 Turret tower.

Dec 5: Upon Login I received a system message that my guardian tower was destroyed
I visited the area and the guardian tower was gone.
I had not /tower terminated
No one in my guild had /tower terminated
None of our towers were attacked, including my guardian tower.
...Basicly, it just vanished.
When I attempted to place a replacement guardian tower, I was unable to as I "was not powerful enough to control 3 towers"
When I hit F8 and Id myself, It shows that I stil control the phantom guardian tower.

Note that my 1 Turret tower was uneffected by all of this.

Dec 13: My Turret tower was destroyed in a raid.
I now have no towers but my Id still claims I have the phantom guardian tower.

Dec 15: I quit Project EDEN
I join Shadow Ops
I place a new Turret Tower in a Shadow Ops controled area.
This brings my tower count up to 2 (1 real + 1 phantom)

I cant /tower terminate. Because to do that would require targeting my phantom tower.
I cant build a replacement as AO thinks I still control this phantom tower.
Ive asked 2 ARKs and 1 GM. (All of 3 have been wonderful and promised to hunt down my phantom tower and kill it)
I just wanted to pass this on to your devs so they can fix it before it becomes an issue for others.
