Im not sure its just me or someone else have the same problem also...
Sprouting 800.000 beans , my rig is online 24/7 , my connection to the network is over 30 all the time, sometimes 65,sometimes 35.
Last time i received sprouts it was 2/27/2018 , now im close to 50% result what the
online bean cash calculator estimated.
I never believed any online coin calculator in the past, those calculator are just a rough estimate... but none of those calculatros are 50% off ...
I think you should not miss more than 2 days of staking with the amount you have.
Are the coins divided with multiple stacks like 100k each?
Maybe each stack is divided to much smaller unless you were combining them regularly and the network weight increased in recent days?
Did you try close and restart wallet?
I tried .... closed the wallet , restart the wallet , restart the computer nothing changed
a sent beans to my wallet with 8x 100000 stacks = 800000beans
sprouting worked fine till feb 27th


You can enable bean control feature from Settings => Display tab => Check the box for Display bean control, then go to Send Beans => Inputs... => Click on List mode.
You can see how many stacks of beans you have and how many coins on each stack.
You can combine or divide there and I saw 100k coins for each stacks were recommended for better staking a while ago, but it could be changed with ever changing network weight.
Your stacks of coins are 25k to 50k now, since your original stack of 100k staked and each stake was split in half.
You can combine 2 or more stacks by checking the box on the far left of coin control window and sending the your wallet address.
I think you have these options for now.
First, leave the coins as it is, since you have restarted the wallet already and it's going to take some time to see if the restarting made any difference.
Second, combine them all as a stack and start staking as whole and it's going to take few days.
Third, you can combine those 25k stacks to 50k or 100k for newer staked stacks but leaving 50k stacks. To do this, arrange the stacks from new to old by clicking on the top of Date or Confirmation column
and check the stacks you want to combine together, then send the chosen coins to your wallet address where your coins are right now.
