I'm using the standard map change dialog pop up for a beam down. This is happening in Foundry; I have not published the mission yet.

My problem is that my captain is already there when the screen loads, the dialog appears a second or so later, then my BO's beam in.

How do I:

1) Get the entire away team to beam in at once?
2) Get the dialog to not appear until after that happens?

I'm pretty sure what your talking about is the Loading Glitch that is a Standard for STO.

As for getting them all to beam in at once. Check what your foundry map has to load. It may be causing lag. Use a Reach marker to trigger the Dialogue.
