我有过类似的case， 4月的BTO，还有几个二楼的，我没去。HDB来信：

HDB recognises that there were limited choice of flats when your turn for selection was due. hence, we have exercised flexiblilty not to treat you as having rejeced one chance and will not count it towards the two chances for the removal of first-timer status in the balloting. however, all your additional chances accumulated from previous unsuccessful applications (if any) will be zeroised.

9月的BTO马上来了， good luck！
