How to fix part not being anywhere near cursor

[SalmonellaDingDong]

I'm sure everyone would love to know how to fix this:

So does ANYBODY know how? Don't say "oh attach the green dots to one another" since that doesn't work as the part isn't even in the buildable area after I pick it from the list.

Is it lag? Lag between mouse updates can delay the positioning of parts.

Other than that, I'm stumped.

[SalmonellaDingDong]

Nope. Smooth as can be. I have to save the ship and restart ksp to be able to put any more parts on.

It looks like some kind of boundaries issue going on whenever this happens, like the entire building area has shifted relative to the mouse position for whatever reason.

Try hovering your mouse over the vessel. The part might try to connect to the plane and not be stuck to the floor.

[SalmonellaDingDong]

I do that and the plane turns green like its going to place it, and then i click only to find the part either under the plane or outside the hangar.

Usually I delete the part and pick another one and it seems to work okay after that.

I get that happening too, thou I'm not 100% sure what I do to fix it. I think I change the camera position so the craft is between me and the pesky part and then try to radially attach it to anywhere. Once attached I then re-pos camera and try it again, but I often find once they start doing that, they keep doing it. So I consider that part dead, send it back and grab a new copy from the list. I never have to restart KSP (for that) thou.

While we're at it what about the center of lift being off to one side for no reason?

[katateochi]

hmmm, that looks odd, looks symmetrical, or at least symmetrical enough to not have the COL so far over to one side.

When building the wing sections on planes I work just on one side (with symmetry obv, but it less important this way), then I remove one whole side from a branching point, (in your case the tank just after the 1-to-2 adapter), make sure symmetry is on and put it back on. That way I know that the whole side has been mirrored and any cases of me forgetting to have symmetry when I placed something gets take care off.

Oh, one thought, you don't have two wings merged into one, just on one side do you?

[SalmonellaDingDong]

They are perfectly mirrored. So I don't get it.

Did you resize your screen? I used to have this problem when I changed the size of the screen after the game started, I think. Once I either restarted the game or returned to original window size, the part stayed on top of the mouse.

Also, I'd think that for some reason the wing piece you're using only provides lift when it is held one way and not upside down. Since KSP does not mirror-image parts so much as rotate them around (even when using horizontal symmetry in the SPH), the problem may be that the wing is placed with symmetry. I expect a plugin like FAR could also play merry hell with the aerodynamic properties of the wing. The issue may be only graphical, though: Be sure to give the wings a flight test to test the lift of either wing.

Usually when making parts this is caused by not having the part in the centre of the scene on export but as this is in general instead of add-ons I guess you're using someone else's parts rather than making you own?
