an update from Clockuniverse on Mattermost:
Wow. What a week!
We have been testing and coding since the issue with the masternode layer started happening, and we are getting close to a very simple temporary solution.
We wont know till tomorrow if the simple solution will work, but we are confident right now!
The original testing was fine on both the testnet and mainnet until enough people adopted the new version of the wallet, so it was a cumulative issue.
Remember no matter what happens to Terracoin, The Terracoin Foundation will never disappear and will always be working to fix and improve it.
I apologize for the hassle that this has caused everyone.
We plan to implement community testing and reform our testing protocols for the next major release to avoid this in the future.
If you are sitting back wondering what I am talking about because your masternode is fine, then you are on an old version of the wallet.
You need to upgrade to at least 0.12.1.8 and re-index because most likely your rewards are invalid.
Remember The Terracoin Foundation is here to help through any issues you have! Please post or contact us if you are having issues!
