So there has been a message from theymos to merit sources stating :
(This message is being sent to most merit sources.)
Previously, you may have noticed that there was a bug in the algorithm which calculated your source merit, causing your source merit to replenish less than intended. The algorithm has now been adjusted to hopefully fix this. As a side-effect, your non-source sMerit may also have changed.
The intended behavior is that if you send x source merit, then you'll get x source merit back 30 days after that send. (Not in a monthly lump.)
Let me know if you still see any anomalies.
Did someone notice any change in his Source merit status?
