So I backed up my wallet on an older PC, then installed on a new PC and restored the wallet there. Deleted on the older PC. I didn't receive any Byteballs this round, even though my BTC were previously linked on the older PC. Is this normal?
No.
What's the BTC or Byteball account you had linked so we can check it?
I'll give you the info this evening, I'm at work right now.
