I acidentally deleted the island settings from my LEGO uefn map and it isnt in the content drawer, so i decided to copy the island settings over from another map but i just get an error when launching session
Lego islands use a different item for Island Settings than standard islands do - It can be found in the content drawer under “Device ExperienceSettings Lime”. Deleting the island settings you copied from the other project and adding the “Device ExperienceSettings Lime” from the content drawer should resolve your issue.
