Some of these numbers are confusing on upgrades. "Faster fusing" supposedly reduces the auto time, but the only info I have is how much time has been taken off. Without knowing what the original time was, that's useless.
Also, when you have reductions by set amounts rather than percentages, it makes most of the purchases in that category do almost nothing. There isn't much incentive to buy them over other upgrades.
why did my autobuilt sentry disappear? Now if I die with superwaves on, I have to die again just to turn it off so I can have time to build that one sentry and that's annoying.
Why do my fleets disappear when I send them to new planets? Are they getting destroyed or something? I sent a colony ship and a cargo ship together, and they immediately vanished from the game.
Mining amount is the total mined per cycle (the top bar), Mining speed is how fast that cycle goes.
