Concerning stake reward, TEK has built in stake reward reduction when PoS diff climbs. It is most likely that PoS shot way up due to the high amount of coin weight hashing on the network. I am not synced up, so I can't tell you what the current diff is, but I know that typically TEK PoS diff has been always kissed its lower bound of 0.03 - anyone have the current diff?
Right now, according to my wallet, it's .001265, but earlier on it was .0002, I believe...
Thats pretty low, but all that matters is what the diff was right at the moment you staked. It could have backed off. This is just a guess of course though. I do see some tweaks made to PoS reduction code, not sure if this would cause the issue or not.
