I have attempted to save my map progress with the workbench tools and End up in the same place every time the tools crash from trying to import a JPG file for map design then I go to load up the tools again and it shows the folder I have created but It doesn't save any of the PPE effects and are just gone and not in the Hierarchy left panel that I had added in any of the previous attempts to start working on my map. For some reason it's completely broken for me and can't seem to get anything but the "terrain" to save but it's just a white blank map with no details from my height-map I have imported.
Possible that the tools are broken for others too but I can't say, Haven't seen anyone else post about this issue. I am on a fresh install of windows 10 and all drivers are up to date and installed properly. Not sure what is causing this. I have been able to reproduce this bug many times, Very present in the World Editor tools.
