Yeah, the price is going up really fast but this kind of trouble could really hurt it, especially when broader audience after launching on Mintpal starts to encounter it... How do we expect to deposit and withdraw coins anyway?
BTW, is there some specific amount of XMR which can be sent and withdrawn safely - that it goes to the intended address without the trouble?
That question is answered at least 4 times a day zone117x is working on it, but if you would like to make it go faster you have been offered the opportunity to fix it on github. The issue has been posted on the monero-project github page.
Be careful when depositing and withdrawing, more so than with the bitcoin protocol. This is still something that needs a lot of help to fit your exact definition of what success/suitable is, but I promise you that very good people are working on getting it up to your standards.
There is no specific amount of XMR that can be sent/withdrawn safely, other than what you personally are comfortable with. Make sure you're using (and who you're receiving from) the updated daemon though! The fee has increased and tx's without that fee will be rejected by the network!
