Been busy messing around in the editor, updating/fixing the collision map, messing around with transparent and animated textures, etc, and as such I forgot to post these quadrants.
Quadrant J16, only thing of interest here is a staircase leading to... somewhere...
Quadrant K16. Again, not a lot here.
I might make a recording/youtube video showing off the island in the editor, which includes all the grass, bushes, rocks, etc that I don't include in these quadrant updates.
