Hi. I am trying to send some firo with electrum, but keep getting these error messages. If I go to “Coins” and manually select some “output points”, I see that with some of the output I keep getting these errors, and I can’t send these coins. So they are just stuck. ![image](https://forum.firo.org/uploads/default/original/2X/4/4fbf8ce5a81ade6b5032a8b9414c88e8c87dd36c.png) ![image](https://forum.firo.org/uploads/default/original/2X/c/cfa099ed17f3ed3912d4eca7646afc3fdd6bc604.png) ---

Are you trying to send coins from a specific address? If so, Right click \> Spend. Then Send as usual. On another note, Are the coins you are trying to spend are masternode reward coins from the same masternode address? ---

I’ve had the same thing happen a while ago, for me it turned out to be a 3.125 firo masternode reward that keeps giving that “prev\_hash” error when those coins happen to be selected for an outgoing transaction. I “fixed” it by freezing those coins, so they don’t get selected in the output points. ---
