I have really no interest into the importer, my suggestion is to just recreate the similar trophies and move on, and tell the member to ignore the fate. The importer is really not that easy because as you said, my trophies app has all the automatic criteria while iAwards has no criteria at all, theres no easy way for me to recreate a trophy automatically with the converter with the same criteria... I had a script to import them as medals but people didn’t like the solution?!
How many people would be interested into the importer and would you mind to pay for it? I have an idea how to solve it , but absolutely no time , so I would probably hire another MP dev with a lot experience with converters to code this.
