Opening map command

[reptile]

Do you open a sp map when your hosting to play it. Because During gameplay I do the open command , it doesnt say it wasnt succesful but nothing happens,no map opens.

if nothing happens, it usually means that you typed in the wrong name
make sure that it includes underscores, and that you don't type in the .ctm extension
for example, to open the first mission, it would be:
open geo_01a

other than that, im not sure what it might be
