Worst "oops" moments in PBW?

[Slick]

This was a long time ago in a PBEM game, but it still hurts. I had a good sized fleet guarding one of my newly established systems. The fleet was self-sustaining and included 2 spaceyard ships. The area was pretty isolated and hadn't had any activity for a while and I had a spy sat in the next system so I decided to mothball the fleet because I was running into a resource crunch. I intended to keep it mothballed for only a few turns. Well, I learned the hard way that a spaceyard ship can mothball itself but can't unmothball itself - you need a non-mothballed spaceyard in the same sector to do that. When my spy sat saw a teensy tiny fleet in the next system it was time to unmothball the fleet so I could apply foot to ***. After a level 8 tantrum, I realized the unmothball problem and that there was no way I could get a spaceyard ship to the fleet in time. You guessed it, the entire fleet was destroyed by a pack of mosquitoes without so much as firing a spit-ball in return.

Never made that mistake again.

Slick.
