Farewell GRIN Cuckatoo31
As of block 826,560, the graph_weight of Cuckatoo31 has fallen to 0, which makes it impossible to solve blocks with C31 — it is no longer profitable to mine GRIN C31 (here was the last block).
Some miners are still attempting to mine this combination, however, and some services are still displaying it as profitable. To help with some of the confusion, we’ve removed GRIN C31 from Foreman.

What Do I Do?
If you want to continue to mine GRIN, switch to either Cuckarooz29 (C29) or Cuckatoo32 (C32).
If you want to continue to mine Cuckatoo31, switch to MimbleWimbleCoin (MWC).
