I have 61 fc's atm (62 unfortunately next tick
)
this is how much metal it says I should get on mining page: 364.841
this is how much I get: 363.587
seems like 60 of them is the "limit". I dunno if it's intentional or not.
Sliekas had liek 145 fc's last round without getting any compensation, so I recommend not building more than 60
