Hi Heiler, sorry for the late reply. For some reason we never get notifications on this site and don't think to check it often.
Unfortunately, there's nothing we can do for your save file.
And yes, the harp language is based on the Turkish language but it was never supposed to be exactly Turkish. Unfortunately, at some point we started making it a little too realistically Turkish based on dictionaries and language resources even though we aren't native speakers, which I'm sure is causing some issues with people who actually speak the language...
Ideally, we would like to make it a good blend of fantasy language with Turkish roots and inspiration. If you have any tips or feedback, we'd be happy to hear it.
