You will have to move all models at least a little bit to add this red kind of bounding box which is required for generating server map data.

The reason is very simple. Most functions in Noggit does not unload their temporary useless data after saving. So, every time you save your RAM usage increases and it starts consuming more pc resources and it slows down your FPS. The problem is the lack of memory management/allocation or whatever it is called. I am not really a programmer, so maybe it is wrong.
It does leak. Everywhere. No saving function unloads its data. Just to test it. Create 4x4 adt map (everything is always loaded) and start editing and saving for multiple times. Watch your RAM usage in task manager.
