All talk about the issue with the wallet, wrong forks, etc. I don't mine 42coin but decided to try to mine some coins solo.
Just found a block and sent coins to Cryptsy. The coins deposited very fast and without any problem, ver. of the wallet v0.7.0.0
What are guys talking about? Didn't notice any problem with 42coin!
Many people (including pools) didn't know about the mandatory client upgrade, so the network forked for a while. It seems relatively stable now.
