Ahh, yes, but in that case, just put it on the spot where you have to set the tent to cause problems.
I like your idea newbie but it again has the same problem as mine; tents wouldn't be available for people to use to heal up if that area was blokced out.
In truth, I don't know the actual size of the uber zone, but if it could be shifted with out requireing a whole new map download, I would say to go for that, or even just move the telport spot down to inside uber zone. I don't actually know if that would require a new map download or not, though I suspect that a script could e written which could delte the tele-out spot in the top of uber, and then replace it down into uber farther... possibly avoiding the tent blocking problem.
Like I said... I'll keep throwing out ideas until this problem can be worked on ;-)
