Yesterday morning i loged in and poped over to the Anzer Infohub. And encountered what first appeared to be the disapering AV bug but as i moved the camera around portions of things disapeared. On investigatingi found a large Invisiprim was obscuing things, I then wandered why autoreturn diden't take care of it. Fuather investigation revealed it was atached to an unresponsive AV.
I then pushed the ofender of the platform
AR'd it sent a warning out over group chanels and because i had other things to do loged out. When i was able to log in later that night it was gone.
On reflection I think it was probly an stealthed Land swoop bot , or copybot that was lost and randomly asigned to a infohub then stranded by a sim failure & the No script and Nobuild settings of the Infohub.
