I received all STAC coins I was supposed to receive without any problems. Starter tokens were converted to STAC before as we all know. But I got all STAC coins. it is not worth much though.
If I remember correctly, the initial Starter Tokens were converted to STAC at a rate of around 1 STC = 10 STAC, so maybe it has something to do with that.
Yes, they converted something and they also claimed there was a miscalculation of tokens leading to people getting too much so they changed it back. I don't know. Very confusing and intransparent.
