It is not true!
In SO wars where i been able build station because have suficient power to destory Reavers - that cannot be destroyed at one atack (no mater if mision is 100% fleet destroyed)
I mine so long and resources slowly down, bud after next day or two i see more resources that i can mine.
An example when i start build mining mase it been at system about 86 000 ICE i mine for 3-5 real days when somoe top players destroy my complet base. And there been Reawers at near 1 bill power.
Bud if you calculate so my mines are upgradet to 5%? I wythdrav more than 30 000 ICE bud system say so there styl 68 000 ICE - Other resources i do not monitoring because i have insuficiend of ice.
As i see resources are slow grow if you do not mine all. But in some systems i see empty bud some day later i see in these system some pieces of resources. Not much only up to 2 000 - 5 000 - 10 000
It is that same star that same system. System been empty only reavers here, after some days back reavers not here bud some resources yes.
