8 hours, save phase 4.
Added a save phase 4 (in line with other full save phases) and hooked all the section 4 data into the play menu visualization.
Portal tracks section 4 pick up as their own distinct resource instead of distributing them into previous phases. To replace this functionality, the portal's function for determining what to build on pick up acquisition now distributes the phase 4 pick ups into the previous phase deficits before working on the door. This lets me better track section performances and be rid of section data about previous save pick up counts.
Pick ups available by section are stored once in the game mode and all calls for pick ups available in a section are a reference to that set. This will make it much easier for me to tinker with phases while maintaining save behavior.
Starting work on the new spawn position selection. We'll see how this goes. I'm very hopeful that spawning on a tile position instead of a random position will open up the possibility space.
