Description

The Update Persistent Audio module has a dependency on a Play Persistent Audio module. When there are two modules in different overview nodes, the automatic fix up can put the Play Persistent Audio module in a different overview node, then the fix-up for moving the Update Persistent Audio will try to move the module to the different script stage and crash the editor.

Steps to Reproduce
  1. Create or open a Niagara system with one emitter
  2. Add an Update Persistent Audio module to the System Update script
  3. Add an Update Persistent Audio module to the Particle Update script in the emitter
  4. Both should indicate the following error: "The following pre-dependency is not met: PlayPersistentAudio"
  5. Click "Fix issue" in the Particle Update script.
  6. The first click creates a Play Persistent Audio module correctly.
  7. Click "Fix issue" again in the Particle Update script

RESULT

The Editor crashes
