Edit: Now that I have a blank model in SE, how do I add textures? I couldnt search for help on textures because the forum complained "textures" was "too common".

Remove "TRAPPIST-1 b" {ParentBody "TRAPPIST-1"}
Remove "TRAPPIST-1 c" {ParentBody "TRAPPIST-1"}
Remove "TRAPPIST-1 d" {ParentBody "TRAPPIST-1"}
I find the problem, Eccentricity is superior or equal than 1 so decrease the value.I tried to create the new planets called Iceqias but the orbite destroy my creation. I HATE IT. I want to remove all that ridiculous bug
There is no bug -- the orbits are doing exactly what you are telling them to do. Eccentricity is how elliptical the orbit is. An eccentricity of 0 is a circle, between 0 and 1 is an ellipse, 1 is a parabola (the object is going exactly fast enough to escape from the star), and greater than 1 is a hyperbola, which looks more and more like a straight line as the number gets higher.
