I'm still curious about where the extra payments are going. I've been staking for ages and never received a 42 staking reward

The 42 PURE stacking reward is something that will be fixed, but in the meantime after looking at the explorer and asking other members, only big stacking wallets get those. If you are stacking with 100 PURE you probably will never get a 42 PURE reward, only 20 PURE. But if you are stacking with 5000 PURE you will get some of those 42 PURE rewards.
Oooo,OK.
