We also observe strange behavior in our wallet. Awards for some blocks appeared a few hours later. Apparently this was the reason for not paying the miners. Although in the statistics, the pool of transaction was displayed. Soft Yiimp is not ready for this behavior of the wallet.
I'm of the opinion that in general the chain needs to be slowed a little. By my count, it's currently averaging a block every 7-8 seconds, which is half the of the intended 15 second blocktime. If the difficulty is nudged a little higher, we might get more stability so that the network isn't constantly trying to give priority to simultaneous solutions.
But that's just my opinion; I'm not a technical guy and I'll leave it to devs to judge what's best.
Yeah, you're right, we're working on it but to not put to much stress on pools and exchanges the update will come out in a week or maybe 2-3 weeks.
