Hallo,
I seem to have reached an issue that I can't fully resolve by myself. I have created a very simple test map but contains a lot of children sector references within the parent sectors and includes slopes, what would be the best way to link these two parent sectors together? I have tried using the Stack Points (THING ID: 9078 && 9077) and also tried Sector_SetPortal[1], but in a much more 'busy' environment with the lower and upper sectors - I am unable to successfully get it to work properly.
If someone would be willing to help me out with this, that would be great! I am completely stuck at this point....
