There is no MacArthur Trophy brown trout under the trophy catches in Lake Miller On the last FSW weekly stream they showed locations of some trophy fish, i don't have MacArthur on my list of trophy fish, i am not sure if the fish is in the game and it is just not listed, i have tried to catch it but no luck so far.
You are right. I have been fishing for him and the other boss fish not even realizing he’s not even on the list. Definitely report that to Kayako which is the dovetail troubleshooting ticket system
