Ignore the defense

As the title suggests, you can have multiple cores in a single sector, but I believe only on specific sectors.

I just want to be clear about this, I am using an old save from a previous beta build of v8 that I loaded in the latest version. However, I believe maps that had not been loaded before have been updated rather than retaining its old state.

Also, I wanted to say that I started checking this because I kept checking reddit for conclusive information on core tiles spawning in Serpulo.

Now if you look in the first image, that was taken from a new map, Littoral Shipyard, but the important information is that core tiles look like that: black and yellow stripes slanting from the bottom left to top right.

In the next image is the sector I checked, sector 76, an Extreme Attack sector.

The next 2 images are the cores which, although I have not captured, still afford valuable information. If you look closely, you can see that the tiles upon which these cores rest are the very core tiles where you can build new cores.

I hypothesize that core tiles only appear in Extreme (or greater difficulty) attack sectors. Furthermore, it's possible they only appear under Foundation or Nucleus cores.
