Laughing at myself--and sharing it with you!

[SilverRat]

So, I'm new to SE, played several full games against the computer--mastered Tactical and realized that it must be discarded to play against other humans. Got used to the strategic method of fighting, and not getting the results I anticipated... but progressing none the less.
Decided to try simultaneous game to get even closer to playing humans (without making a total fool out of myself) and accidently glassed an allies Homeworld--oops-86 satellites and a fleet did more than the 'oppression' role I had intended... so I went back to the last save and changed the strategies, removed some sats... etc - (do over! sorry guys...) tried to figure out the right methods of not killing 98% of their race... BUT (most of you are shaking your heads or laughing WITH me now) odd things were happening to me. . .
1. I tried it several times until I didn't wipe them out.
2. When I finally noticed it my storage of min, org and rad were all filled to max. . .
3. the year was 'jumping' WAY ahead of my 'current' year...
4. I finally realized in a simultaneous game you really can't go back for another try-what happens has happened, saves don't matter- the game marches on each time you press the "Next turn" button. (lucky the research was on renew projects!!!) So, now I have stockpiled resources, no new ships, many 'obsolete' ships on the front lines, and a bit of catching up to do.
LOL good lesson for me- is there a way to go back or am I right - whats done is done, and move on?
By the time I realized it I was filling out a turn and the date would change by 1.8 years--18 turns of spinning my wheels and wasting resources!
The comeback will be fun, hope you at least smiled at my mistakes, it did make me laugh out loud.
