Thx to guy at Telegram, just send few fractions of coin to Cryptopia and your missing coins will show up.
Tks man! I sent 0.2 bwk to my cryptopia wallet and work just fine. My coins showed up!
Well, it's good there is a work around. But having to send a small amount of coins for your old coins to show up certainly isn't an ideal fix. This whole ordeal certainly brings the competence of the Cryptopia IT team into serious question.
