Why is it mined on your pool back from block height 3200 etc a few hours ago

While blockchain was already at block height 39000 ? How is that possible, did you build a fork of the coin oO
Our main nodes become unsynced due to a server issue, so was trying to force it to resync but appeared nobody had a fully resynchronised node,
Our nodes are now in sync again, although the blockchain has lost around 500 blocks.
That doesnt answer my question, something's wrong with your coin, read above please and also about stuck transactions
