What do you mean by smaller improvements again? At the rate my 12 large cargos are hauling in resources, my shipyard's backloged for days, my research is going at full, and I've been building storages, missile silos, solar panals, and mines continously. By the way, I actually did spend all my metal and crystals a few hours prior to that when the guy sent a fleet maybe 8 hours earlier and I fleetsaved and sent him a message. Yeah, raiding like a fiend gets me a lot of stuff.
As it is right now, It'll be at least another three days until my shipyard can start reproducing my cargos and probes, and I do want to build my 8th level of shipyard for bombers and plasma turrets, which WAS going to be availabe within days.
Well... At least I've learned from this. Now, I'm going to get myself an colony that's far enough from the big fishies so that I'd have at least an hour or two of warning before a fleet comes knocking. And that colony is where I'll be putting all my backloged fleet/defense production, nearly my entire fleet, and very little resources that stay. I'll have to produce a few more dozen large cargos for constant fleetsaving, and although I'll still station a dozen large cargos on my homeworld for raiding, the resources I get will either be immediatly shiped over to my production colony for immediat use, or, if I'm saving up something for a particular building or research, be constantly in transit so as to keep it from sight until I got enough to use.
