Hello, Iskandar!
Saving in a planetary battle is impossible, because in this case savefile can be too big, or little damaged. You can't save in planetary text quests too.
As I understand, you have Space Rangers 2: Reloaded. If I make an error, Your trouble can be in one nasty bug: then you press an "E" key on your keyboard and at this time you have selected robots without Nuke Bomb (or however it named in English version(I have a Russian)), a game wiil crush.
I think, somebody will help you.
Hope someone is still around to answer this....
You can see only English part of the forum, but you can't see Russian part of it. But I'm can seeboth. Everyday hundreds of people visit this forum, and I hope, someone there really can help you.
P.S. My English is very bad
