I am having several issues with this. First, groups I have joined keep asking me to join their group before I can fish, but when I try to rejoin, the option isn't there. Also, I don't understand the linden earnings and no one will explain. It'll say that I have earned such amount for fish, but after hours of fishing, I go to an ATM and it says I have 0 lindens. Not sure I understand. Am I earning lindens or not?
