Possible bug in 1.49?

[Chillum]

I've been toying with a Star Trek style Genesis device, but I'm missing a couple of important elements, hopefully someone out there could help ?

I'm basing the device on the following attributes..

1) Change Atmosphere in single turn
2) Increase Planetary value
3) Component destroyed on use
4) Planet must be present to use device
5) Make the planet unstable

I was hoping to increase the planetary value to an absolute amount, but I'll settle for an increase, but I'm having trouble with numbers 4 and 5.

Any ideas ?
