UMG WebBrowser - failed to load

Hi Rudy, we are experiencing this as well. Our detailed steps are as follows:

  1. Have one person add the plug-in and make a UserWidget on an actor that uses the web browser widget.

  2. Check-in that work.

  3. Possibly relevant: upgrade to the latest hotfix version. In our case 4.12.3 to 4.12.4.

  4. have another person add the web browser widget to an existing user widget archetype.

  5. Compile and save.

  6. Close the project and reopen it.

  7. Result: The widget that was added by the initial user still works fine, but errors about cannot find file for asset /Script/WebBrowserWidget are thrown for the Web browser UserWidget that was created by the second user.
