Something went really wrong with my model Inventor 2020

So, I'm making this funnel series with volumes between 20 cubic meters to 200 cubic meters. I am making it from 1 base multi-body part with some formulas to calculate the model sizes. If I'm done with the first, the others will be quicker to make. However, a problem occurred at this point. I tried changing the volume, and it broke, which I suspected to happen. I didn't suspect the scale in which it would happen. There seems to be a cyclical dependency issue around Sketch12 and ExtrusionSrf10, but I can't seem to find out what. 

So here are a few of the problems I find:

 

1. when trying to move the EOP below ExtrusionSrf10 it gives me a cyclical dependency message and I can't go through

2. I can't edit/open Sketch12 when I click on it I need to choose a surface which start a new sketch 

 

3. I can't edit or see my Sketch blocks in Sketch5 

I have removed a few links between dimensions in Sketch12 so that it does not have links to other sketches but this doesn't seem to have solved anything. 

 

I'm Using Inventor Profesional 2020.1 (We're not able to upgrade to newer versions of Inventor due to old computers)

 

I've included the model, so I hope anyone can find a solution. If you need more information, feel free to ask. I don't really know how to explain the problem at this point. 

Btw: It worked before I changed the Volume from 80 cubic meters to 105 cubic meters

@Enroc 

Can you recover an OldVersions of this file?

I suspect that the entire procedure can be significantly simplified resulting in a robust solution.

Well, there is some progress lost doing that, but that's okay.
