In other news...
What the devil would make my SC interest payment go into a status of "conflicted, Generated but not accepted, mined?" The details being "Generated coins must mature 510 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours."
Why would interest be subject to loss by mining standards?
My guess would be that when you stake a block it is sort of a race condition. It gets applied to the chain, but if someone else staked the same block a few seconds earlier you would lose the stake. In that case your coin age would be reset so you really don't lose anything and it will try to restake again. A similar thing happens in mining when you get mine a block that is solved before your work is accepted.
The devs can confirm or correct this.
