It appears we had a prolonged chain split yesterday caused by a transaction with unusual values. In that scenario, it is not unusual to lose mined blocks when the two chains converge. However, no other transactions or coins should be lost. You may need to re-index your wallet or replay transactions for things to go through, but there is no way for transactions to disappear.
I recommend checking we're all on the same chain now - use Fuzz's block explorer as a reference to see if you have the same latest block -

Use the latest source from the master branch if you're compiling your own HOdlcoin software.
We'll need a new point wallet release as this bug is a serious DoS vulnerability.
