When I ran FO3Edit's error check on FO3 Wanderers Edition - Optional Free Play After MQ.esp, it returned the following error:
MrAutumnName "Mr. Autumn" [MESG:00FF1234] -> Missing required members: Description, Icon, Flags Above errors were found in :GRUP Top "MESG"Above errors were found in :[15] FO3 Wanderers Edition - Optional Free Play After MQ.esp
Is this error benign?
Yeah that error is benign. Fo3Edit's error reporting function is very fairly thorough, but not everything it reports is a real error.
It'll report Above errors in Broken Steel for example as well, because it can't identify certain flags.
