Exception when copying a process node with incoming links (CTRL+SHIFT+D)

sebescudie · April 16, 2025, 7:25pm

Hey hey,

In the latest preview, selecting a process node and pressing CTRL + SHIFT + D throws an InvalidOperationException : "Sequence contains more than one matching element". Nothing happens in the patch, but the following exception is logged to the Console.

Repro steps :

Using 7.0-0314, open GammaLauncher here
Navigate to LaunchTabRuntime (you can search it with CTRL + SHIFT + F)
Look for the Save Bat File frame, select the BuildBatFile node and press CTRL + SHIFT + D
