It just means there are people staking before you. Staking is very similar to mining... You are going to get less coins if you mine/stake with less power...
You stake power is determined by how many coins you are holding in your wallet.
We just expected this(the highlighted) from the first post.
Reason for update:
We have been experiencing a lot of network issues that should be fixed in the new wallet.
Its possible that the network has been connected to a whole other network, and this could have affected users with a low amount of coins who is staking.
By releasing this update, we should eliminate a lot of the orphans and be able to have a more stable network.The update will be released tomorrow at 20:00 GMT + 1 and we hope everyone will download and install the new wallet there.
