h3. Reproduction Steps:

1. Open the attached project.
2. Go into the project settings and into the Visual Scripting settings.
3. In the Node Library, add the assembly NewAssembly
4. Enter play mode or perform any action to trigger a domain reload.
5. Go back to the Visual Scripting settings and look at the Node library again

h3. Actual Outcome:

NewAssembly is removed from the Node Library.

Note that if you add a Type Option from the NewAssembly then it would remain in the Node Library after the domain reload. However we encounter a different issue. 

If you add NewAssembly to the Node Library and New Behaviour Script to the Type Option, if you remove them and trigger a domain reload, NewAssembly reappears in the Node Library.
h3. Expected Outcome:

After the domain reload, NewAssembly should still be in the Node Library
