I write here for the first time.
I'm performing some experiments to clarify the emblem system. In the experiments, I have obtained a result. The growth of emblem is different between Survival mode and Grief mode. I have already reported it to viewtopic.php?f=137&t=33098
1. When a new account is played at only Grief mode, the emblem is not grown.
2. The emblem is changed from single bone to shotguns suddenly, when the fully-grown account is played only one time at Survival mode.
3. When the account is Shotguns emblem, the emblem is not changed by increasing DOWNS.
Now I'm investigating the boundary condition to the Shotguns emblem. I'll report it, when I get the result.
I'm glad if this is helpful for everyone.
