Crash There is a soft crash when resizing wings on 2x2 symmetry vessel

[Nenovike]

Reported Version: v0.2.1 (latest) | Mods: none | Can replicate without mods? Yes 
OS: Windows 11 | CPU: Ryzen 5 5600X | GPU: Nvidia RTX 4060 | RAM: 32GB DDR4

 

Severity: High - soft crash. Tou can't Launch, random buttons stop working, after exiting to menu you won't be able to load or start new game.

Frequency: Reproducable

Description:

1.     Create new vessel.
2.     Start with Mk1 Command Pod.
3.     Attach TVR-200 below it.
4.     Rotate the camera te the left 90 deg, so you can see door with #04.
5.     Using 2x symmetry (pressed X once) attach FL-T200 to the LEFT node (marked on SS).
6.     Still using same symmetry copy fragment of the vessel below Command Pod (TVR-200 and two FL-T200s).
7.     Rotate fragment 90 deg (pressed E once) and attach under the LEFT FL-T200 (marked on SS).
8.     Still using same symmetry add LPS-250 to the CLOSER RIGHT FL-T200 (marked on SS).
9.     Your vessel should look like on the screenshot.
10.     Using wing shape menu change wing span to something like 0.15.
11.     With wing shape menu still visible, save the vessel.
12.     Launch.
13.     Revert to VAB.
14.     Using wing shape menu change wing span to something like 0.18.
15.     With wing shape menu still visible, save the vessel (overwrite).
16.     Save menu should still be visible - that's the sign you reproduced it.
17.     Enjoy.

Launch doesn't work anymore, cannot edit the craft. Most buttons don't work. If you exit to menu, you cannot create new game, loading a game will get you stuck in loading screen. A lot more stuff probably happens, but i did not try most options.

If you press CTRL+Z and CTRL+Y to "reload" corrupted craft after step 16, you can grab the FL-T200 with the "original" wing and try to reattach it. You will get "VAB/Messages/IvalidSymmetryAttach".

That's the simplest craft I tried to reproduce the bug. Seems like it works only when you attach the wing to the part that was created by symmetry, so directions in the guide are important. To open the wing shape menu I was using the "original" wing, not the one created by symmetry but i don't know if it matters.

The bug was also present in v0.2.0.
