Gameplay tips & tricks

[CaptainAL]

The ship upgrading has been a source of frustration for me. I think it may be a bug - I am sure that others here must have encountered it. Here's what happens:

I give the upgrade orders. [when this happens there's usually pretty many ships and a large amount of resources involved, with maybe a stellar manipulation upgrade or two] I add up all the resources needed and check my STORAGE amounts to make sure I have enough. Sure enough, I have plenty because I have been good at building many storage facilities. Now I also convert some resources, because I have so many extra organics and radioactives but am light on the minerals. I am careful NOT to convert more organics and radioactives then are available for the upgrades. Great, good to go... next turn I'll be ready to move...

NEXT TURN: Sh--! Not one ship upgraded. "Not Enough Resources" message for every one. But there are all the resources - still in storage.

Anyone have this happen (or am I just really burned out and not calculating everything right -- nine or ten times now)? Sometimes it happens, sometimes it does not. Anyone know how to avoid it? It has screwed me up so badly that now I never convert and upgrade in the same turn, unless I really don't need the upgrades that badly.
