Hey Puzzler, I think a few other Epic folks reached out but I’m commenting for anyone else.
If you’re trying to convert from FNC to UEFN please make sure that all accolade devices in your map do not have any newlines (i.e. all text on one line) in the Device Name or Description for the time being. We’re working on a fix but in the meantime this is the easiest workaround we’ve found.
Sorry for the hassle.
