Seeming Bug

Often when I am working on a very complicated sketch the program seems to become confused and says my sketch has failed when in fact it hasn't. For example, it said my sketch had failed when I turned a regular line into a construction line. Another example, I attached a curve to another line and made the two tangent. The line was already defined however the curve was completely undefined and had zero other constraints. There are many more examples of this I can share but it most often happens when a sketch of mine has a lot of lines, is fully defined and I add something to it.

More than likely, the last entity that was added also had some automatic constraints which conflicted in a way which over defined the sketch. Try showing constraints. There’s probably one constraint which can be deleted which will fix it.
^ +1. If that doesn't help, share a document so we can look at the issue.
I tried all combinations of ^ + 1 and nothing seemed to work. I am also not fully sure by what you mean by those. I am I just supposed to press the keys? If so, I did, and it did not work. Below is the link to my model. The sketch where the issue is easily visible is Sketch 81. One thing you can do to bring about the issue is delete the 8-degree angle and this makes the sketch red.

What do you mean? So I would just press the characters ^ and 1 if my sketch becomes overrefined?
It is not because as I explained, when I added a line, the sketch did not say it could not be solved but when I tuned that line into a construction line the sketch could not be solved.
Sorry for the confusion - I was just seconding Simon's post. 😛 Can you make your document public?
Hopefully this works.

@_anton if you could lmk when you get the link from my last comment that would be awsome!
Can you make the document public (I can't and shouldn't edit the original document, and it's impossible to inspect the sketches with a view-only link) and specify some reproduction steps?
You might just be hitting the limit on the number of constraints in a single sketch.
I've run into it when doing a sketch laying out a bunch of text. And it caused the sketch to become "randomly" unsolvable when adding anything even with no constraints.
The solution is to break up your sketch into several simpler sketches.
There is a limit to the number of constraints in a single sketch??
Yes (don't know what it is), not usually an issue but when sketches get very complex you can hit it...
