I'm getting this issue too while trying to mine FTC; I'm sometimes getting ORB, or GBX, or VIVO. Would anyone know if all these coins being sent to the FTC wallet I've set up in my miner? -- can a neoscrypt wallet handle any kind of neoscrypt based currency? or are these coins being sent to my FTC wallet but essentially they are being lost? If so, how can I setup my miner to make sure the other neoscrypt coins are being properly stored in a valid wallet if yiimp switches the mining type? If these additional coins aren't being lost, how do I go about seeing how much of each type I've mined?
Sorry for the slew of newb questions, just trying to figure out how to be a better miner.
