I came across the same problem! I simply started over with a new account (Bonus: I friended people who actually
water their trees!) and just waited for nova to tell me to catch something before I caught it! Sure. It's annoying, but hell! Why not! If you ask me, the most important part of it is that you can't release any of your Mogas back into the wild! That would fix the glitch, and make it more fun! There could even be a little cut scene where you watch it run off into the sunset!
Anyway, if it bothers you too much down the road, just make a mule account and start over!
...I want friends who water their trees....
Anyway, having two accounts seems... odd. But i see why some people do it. but that doesn't solve the problem of having multiples of mogas. I'll just stop catching them until i'm told to catch them.
