The video of what happens: Hello. Sorry if NWN discussion is not allowed here, but I've looked other posts and other people talk about NWN and I couldn't get any answers from other NWN communities, so here we go. I tried to make a doorway that connects a house inside and outside in NWN EE toolset. However, error occurs when I do that. How do I fix this? I've tried several times but it's all same. I even tried connect the door not both ways, but only one way or I tried very tiny map, and I didn't run any other program beside NWN toolset but error occurs and it turns off. Anyone knows how to fix this? Thank you.
