Question.
I just recently tried to make a map pack but I am curious because my tester said that she got into the Entrance map and another map connected from the Entrance map, called the Den.
When she was done exploring the Den she headed back towards the Entrance map and it said "Cannot find Map File" or whatever.
I did connect the portal two ways as far as I can remember. It also works for me. I can head in and out of the Den and the Entrance as I please?
Why is the portal only one way for other people? How can I fix this?
