[0.90] Ships construction breaks after reattaching an undone part stack

[keptin]

Repeatable bug, vanilla 32-bit version of 0.90, bug also present in 64-bit 0.90.

One of my methods of replicating stacks of parts is to pull off a stack, place it to the side, and ctrl-z (undo) to replace the stack on the ship, leaving a duplicate stack to the side in the editor. When doing this in 0.90 and trying to reattach the duplicate stack, something borks and fuses the stack to the ship in what I'm guessing is a now broken nodal part structure.

Hmm. Undo has always been really flaky, and I'm not sure if it received any attention this update. Any reason you can't hold MOD+Click to copy the stack without pulling it off? Not that it fixes "undo."

Cheers,

Oh, I never realized Alt+click copied the part stack! Thanks!

I also have this issue. It appears that using undo at all is extremely likely to put the game in a state where the craft cannot be launched and parts that are added or removed do not appear properly. In addition, exiting the VAB/SPH in this state is impossible, though saving your corrupted craft is possible. Loading the corrupted craft then replicates the broken game state.
