if u did adapt spliuttreshhold then the coins will merge together to bigger pile next time they mint
yes small coinpiles can need many days to find a block
just give it a few days
just keep a mind if a 80 DMD pile would find 25 blocks a year it would be still above 25% a year
so that such a pile need on average up to 2 weeks is total normal
The problem is none of the coins are moving to stake. It hasn't staked sense the last wallet update. I am not sure what to check to make sure it's working correctly.
does the blue diamond - bottom right corner of wallet say 'staking active' when you hover over it ?
