Eeek! Didn't mean for a simple (that's strange) question to be so prominently displayed in a popular thread for all to see!
Quick Stone Mill, post another strategy article so my silliness can be buried in the sands of wisdom.
For those of you who like trying to figure out strange bugs here is the complete situation:
1) I was playing a game using the TDM modpack (Version 3.00). I won the game (400% of second place) a few turns before getting Matter Gravity Sphere II. Since I had never made a planet before I wanted to keep playing and see how making planets worked. I built my planet maker and used it and ever since then the Matter Gravity Sphere II has not been repaired either by the repair bay I on the ship or by taking it back to a shipyard. I have reloaded this saved game and the situation is still the same. That particular component never gets repaired.
2) Started a normal 1.84 game with high tech and built a planet maker quickly and tested it. The component gets repaired fine by the onboard repair bay.
3) Started a TDM (Version 3.00) game with high tech and simultaneus movement and repeated experiment. Component gets repaired by on board repair bay.
4) concluded that it must have been my "Victor" status which prevented the repair bay from functioning in 1). But Fyron is right, this doesn't seem to match with other experiments I have done where I started a game with just one empire to test something out.
So I'm completely puzzled by this bug. But its not important!!!! Back to the wonderful strategy articles...
