Are there any known bugs in this release? I have installed it and tried to finally claim a remaining portion of my Iotas, but what I got is pretty strange.
Opened the "Claim process" dialog, entered old seed, then the new seed (different one) two times. The button indicated "Claiming" for some time, then it showed something like "The seed contains 212 Gi", then after some time button changed to "CLAIM COMPLETED" in nice blue color.
However when I login using the new seed, I see balance is zero.
Well, I logged out, and did the claiming once again, absolutely the same procedure, just with different new seed. Both the process and result were again the same - it reported "The seed contains 212 Gi" (regardless of the fact I already claimed them!), and "CLAIM COMPLETED". Then again, I logged in by new seed and saw zero balance.
Am I doing something wrong? The procedure is extremely simple, I cannot see what I can do wrong there.
BTW, I used
http://service.iotasupport.com:14265 as the node, just in case if it makes difference.
Would appreciate any help, or RTFM if needed

You should look at the transaction history if there are any pending transactions. If there are, just wait until they're confirmed(it should in 24 hours), otherwise balance will show up as 0. The way you described it, first attempt should have been valid.
