pre: I love to play without Secondary and Tertiary Color Fluid Patches and without colorfulness shape (as in Colorfulness 0%)
i noticed that the Ck Shape (which is need in jobs and Pre-Milestone shapes) is spawning so rare that the game becomes hard if you need them)
Here are my Test Saves and results:
Test 01 : Default Settings:
Ck Asteroids are there, but no black Fluid Patches
Also other black shapes where popup : Wk, Rk Sk (all Rare, intended?)
Test 02 : Colorfulness to 0%
Ck Asteroids only 3 times around the home-Grid from 9|A 0|-I till -10|A 0|K,
then nothing (searched; 50|A 0|-BW till -50|A 0|BY)
Also no Black Fluid Patches
Test 03 : Default Settings but Spiral off
Ck Asteroids are there, but no black Fluid Patches
Also other black shapes where popup : Wk, Rk Sk (all Rare, intended?)
Test 04 : Colorfulness to 0% and Spiral off
Ck Asteroids only 3 (same Locations??) times around the home-Grid from 9|A 0|-I till -10|A 0|K, then nothing (searched; 50|A 0|-BW till -50|A 0|BY)
Also no Black Fluid Patches
after tests, my opinion:
In Insane Mode, without colorfulness/tertiary colors selected, spawn Black Fluid Patches and more Shape Asteroids that contains the Ck shape anyway or forbit the (C)ROS algorithm to make shape with Ck or ck (Red. As of now: seams fixed, but still happen in CROS), as the END Milestone can be got from the research Station
Or:
In whatever mode that has Ck in (Pre) Milestone let Black (or White in RYB) Fluid Patches spawn (whatever setting is selected)
