Description

When a level's blueprint contains a multicast function with a parameter, Server Traveling to that level, triggering the multicast, Server Traveling to another level and then back to the level that had the multicast called on it will trigger a crash with the following error:

206]LogWindows:Error: Fatal error: [Link Removed] [Line: 5431]
[206]LogWindows:Error: Package /Game/LevelA was reloaded before it even closed the linker from a previous load. Seems like a waste of time eh?

Steps to Reproduce
  1. Open the attached project
  2. Package for Win64
  3. Run the .exe on a computer and run the command: open LevelB?listen
  4. Run the .exe on a separate computer and run the command: open [ip address of server computer]
  5. On the server, run the command ServerTravel LevelA
  6. Press H to call the multicast function
  7. On the server, run the command ServerTravel LevelB
  8. On the server, run the command ServerTravel LevelA

Result: The game will crash with the error message in the description
