Summary

When migrating things from within UEFN, you need to restart UEFN for them to show OR get validated when you launch live edit:

  1. UEFN to UEFN migration will make the content not show unless you restart
  2. Dropping .uasset in a UEFN folder will make it show, but the links between the references will not work for those files, making validation fail upon launching live edit. Here is an example message of it failing due to these links:
