I'm also having issues with sending to a Cryptsy address (latest wallet), A small transfer worked perfectly (<100), but a larger one (approx 50k) dissappeared. Both did get thousands of confirmations, but the bigger one did not show up at Cryptsy.
Now what? Is there something I personally can do? Or do we need to wait for another wallet update?
I'm getting confused by the talks about forking, chains.. an address is an address, right?
If you can't understand what is going on you'd better wait for new wallet from dev. He promised to do a new one.
