This might need urgent attention if this is beginning to effect converted from 1.0 to UEFN.
My team leader on the TrinityPeaks open party world project has been receiving this error message consistently after loading up the project on UEFN and trying to start sessions. Another team member has tried to fix it using the text editor but the error is still there.
A creator, Paradox has mentioned 1.0 maps have an issue where stuff on the backend gets duplicated or messed up when converted to UEFN. It has happened to one of his teammates.
I hope is a solution or a bug fix.
Thank you
