IMHO nothing is wrong, just big volume of NAVS being sold and bought, so it takes couple of days. In the long run you should get 5% exactly, nothing more nothing less, so calculate it for yourself.
If the percentage was much higher than 5% for some time, you will receive nothing for couple days.
You actually have a very good point there. Maybe more people are now staking due to the rise in buy / sell nav and you are right that 5% should sort itself out in the end. Thanks for a different perspective - it certainly makes sense.
Still no idea there that weird nav address in my wallet has come from it says mined and its had its confirms?
Still no stakes, but I will leave it another couple of days .......
It could be one of your "change" addresses. You could check the block explorer for that address to see where the coins came from.
