Well I've somewhat given up. I decided to restart
After about 20 hours I've completed my map. I love it and should learn what others think soon. Thanks for the help.

ok, well I'm totally new to mapping with hammer. I am working a a relatively large map. I created everything and try to build it, but there's an issue. I read this post and I tried opening the .map file like you said, and there were like about 200 objects i didn't create. I was wondering
1 how they got there
2 why they are out of the mapping area
3 how I will know which ones are safe to delete
I know i'm a noob at this, but I somewhat understand mapping. I've played with the unrealed many times. I pretty much only have this issue. Thanks if you have an answer . . .
