[Alt] Part reproduction error

[Judman13]

Kerbal Space program 1.0 part duplication error when using [ALT] + Click to duplicate part. Steam updated stock version. New Career game after update. No Mods.

Tried to use Alt click to duplicate the Elevon 1, but after clicking the part did not appear and all other parts became un-clickable.

I used [Ctrl]+Z to undo placement and then duplicated part appeared placed where I originally wanted it, but does not have any hover-over action and does not respond to undo and redo commands as shown.

Error has spread to other parts. Any part that I try to edit now becomes unusable. Parts now stuck to mouse. Pressing Delete will not get rid of part. Cannot exit SPH with part stuck to mouse, had to force quit game.

Seems a restart of the game has fixed the error. At the moment I cannot reproduce.

Please let me know if the permissions need to be changed.

Just trying to help the community I have began to greatly enjoy!

This may be a craft-specific error. Could you provide a screenshot of the craft, or ideally the simplest craft that can reliably reproduce it?

Not that it fixes the copy problem, but also Undo is quite buggy. I would recommend avoiding using it, especially to replace parts that were pulled off.

Welcome to the forums!

I agree with Claw. Using of undo functionality can cause lots of problems especially when working on large ships with lots of parts. In previous versions it caused me several game crashes, part duplications, unclickable parts, huge memory leaks, and even compleete game crashes. in one case I was even stupid enough to save the bugged ship which caused the KSP to crash every time I tried to load it.

The craft in the beginning of the video was the craft that produced the error. I have tried to reproduce it, but have not been able to.

I was hoping there would be something in the logs that would point to what happened. However, I am not savvy enough to track that down.
