Number one: SFA isnt a usuable map for foundry missions (Customizing and adding stuff))
Number two: SFA holodecks arent missions triggers, so you cant have a Kobyoshi Maru start in a holodeck, making Mission triggers Holodeck 1,2, and 3 would be awesome.
You can see all this on tribble where foundry is up
About Foundry on live, Be patient, Complaining has a 25% chance to proc it being down longer then it should....id rather have it good then bugged.
1)social areas have never been a place we can do so on to my memory, and SFA is a social area
2)As Kirkfat discovered there is a ferengi working a console by one of the holodecks that you can use as a mission door for such events.
