Maps no more updated? Problem with maps--

[IWT]

Hey guys! It's my first post in these forums, and I'm working on custom story. I faced this problem:

I can add new scripts, entities but my problem is: Every new static objects I add in, like walls and windows, are not appearing in when I try to play my map. I built another map, and all it has is the base, simple plain room without anything, which I created a long ago. I added a window in my first map recently as well, but it's not there, but the old wall it had on it's place. Lights are not showing either which I added recently.

In addition, the walls started to go buggy, every entity is just going to be sucked in.
