I either have an understanding or a technical problem, I don't know yet.

I work in part design and combo view most of the time. As soon as I delete an older step, that has to do with edges (for example a fillet), all the steps I did after that send an error. I would understand this as long as the error-giving step is based on what I deleted, but it also happens to steps that have nothing to do with future steps. Also, the 3D view doesn't update anymore. I have to delete ALL the next steps I did and have to redo all the tasks I did, just to get back an updated viewport.

Since it is unrealistic to expect one hasn't to overthink an edge I can't believe I did everything right. Often the problem sits in front of the PC... Maybe someone could explain what I did wrong.

This is an example, no errors are given

i related \"Wanne Fillet\", which is the fillit on the inner edges of the main surface in the middle. it is the second last step I took. the last step is for the screws and hasn't anything to do with it. But there is an error and the 3D-View didn't update the change I made by relating the step. So I have to delete the last error-giving step called \"Schraubenlaschen Fillet\".

​

So I had to delete the last step called \"Schraubenlaschen Fillet\". Now there are no errors anymore. I promise there were no references in sketches or anything. The two steps don't have anything to do with each other, but still, they interfere with each other.
