Soo after about a year into playing the game I've decided to actually go ahead and earn all the badges. So like between bronze silver and gold badges for example the letter badge where bronze is 50 letters and silver is 100 letters. If I send 50 letters and receive bronze do I send another 50 that eventually adds up to 100 or do I send a whole new 100?
^Yep to these, they stack so you don't start over again after each one. The only one you need to replenish is the money one if you spend some, it doesn't keep adding up if you spend it. I learned this the hard way, should have just gotten the money badge before sharing my money between my three side characters to build their houses. :[
