That's gonna be very shortly timed between summer and fall event.
@kafidav no one knows yet, it's accessible on browser on Beta server. On the app it's usually a long while later. Often near the end of the beta tests.
As for feedback, please swap medals with random units from lvl 7 for example:
Lvl 7
Coins + medals / 24h
Chance lvl 7: 25% 20fps 25% 55 goods
30% 2 random units 20% supplies
Chance lvl 8: 35% 30fps 28% 70 goods
25% 3 random units 12% supplies
Chance lvl 9: 40% 40fps 32% 85 goods
20% 5 random units 8% supplies
In this way the hideout becomes more worthwhile and players seeking medals can
getting them anyways. Some other event buildings offered similar productions for
example and the chance to gain random units is also more in line with the theme.
A chance to attract new merchants for your army, plus because the random units
is very rare it makes this building far more a point of interest to talk about for the
community.
