You can update the referal program
You have a great idea for a referral program but the implementation is bad. If someone gets a quest 2 after trying a friends and starts to load it up and activate things, they loose out on the referral program because they started before their friend sent them the link. This shouldn't matter and should be easily controlled to allow only one referral credit per account, no matter when they get it. after that the referee credit would work as normal allowing me to refer friends as well and I could gain access to the credit once they get a quest, etc.
The only way for me to ********* a quest that is a week old is to reload everything and start over.... which doesn't make any sense...
Again great idea, very poor implementation....
