Bringing topic back to life...
I doubt this is possible with current client. Players blisps would be fixed first in that case. Only option is maybe to leave just a checkpoint on the enterance.
I dont like saying this, but It is possible. Seen it in action. It is very possible to make any Icon to appear as local. It may not be the same house in white circle, but it can be house in green circle.. atleast thats what I've seen.
So now I believe that just couse of this Issue, house system progress in stuck..
And my personal view on blimps with flags.. flags annoy me too ^^
