We have bank and exchange consoles that multiple people can use at the same time. Why not the transporters on New Romulus? It might be something the monkeys.......I mean, the developers overlooked.
And another thing: This has happened to me at least a couple of times. When I use the transporter my bridge officer doesn't beam with me and he ends up running all the way across the map to get to me. (I'm amazed at the pathing and AI in that aspect though. )
Also I have seen player's bridge officers stuck in the ground near the transporter at Vastam Peaks (not the mountain pass transporter north of that).
I went to the Delta Quadrant and the Kazon stole my stupid T-shirt. Also, my pet hamster that died when I was a kid is now a Kobali.
