Uncertainty
Some machines need uncertainty resolution, by animate observer, to operate properly. (Don't ask why, maybe they just feel alone.)
The status is available in the multiblock controller as a 3x3 grid of LEDs.
You just need to balance the lights around the focal points in the uncertainty hatch. There are 9 focal points in total, active ones are either green or red, you don't need to balance inactive ones.
If you take a closer look at the LEDs you will notice that they have 2 shades on their surface. Darker color denotes the affected area by the focal point. Only that area needs to be "balanced on top of the focal point" to satisfy it.
In the example i have highlighted the effect range of 2 focal points.
Buttons on the sides are used to pickup and replace 2 uncertain values.
Sometimes it might be impossible to balance the focal points. Try waiting or replacing the hatch if u dare. (Yes this is a feature.)
