NOTE: This is a modified example to show some of the conditions surrounding the problem. I can make it simpler.
If you issue a NOVA for the star you are currently at, then immediately issue a TIME command to make it blow up, the image of the planet is not displayed.
In the sample code, below, I set up a very specific star with a grassland planet. In the single page, I set the planet to frozen1. I then set off a NOVA, delay 1, radius 0. That makes a nova which does not blow up a ship, but goes off almost immediately. (This is a desired effect.)
Then I do a "TIME 1" which actually makes it go off immediately!
It works perfect, except for one tiny exception. No planet picture.
I threw in an extra CHNG 0 PLNT frozen1 command just for grins, but it has no effect either way on the results.
I've attached an image of the happening to this post. (You'll see a cool nova shockwave in the background of the window.)
And... yes, if you guessed, XPLR 0 2 doesn't work in this situation either. So you have to go back and re-view the star system in order to mark it explored.
